Best Laravel freelance projects

PROJECT OVERVIEW

We're building a self-hosted platform for issuing and managing NFC tags and dynamic QR codes tied to permanent, trackable public links. Each physical device - an NFC tag or a printed QR code - points to a permanent public identifier that can be redirected to a different destination at any time, without reprinting or reissuing the physical device. The platform is for businesses that distribute NFC/QR devices at scale (product packaging, review-collection tags, asset labels, and similar use cases) and need reliable, high-volume redirect infrastructure, a management dashboard, and subscription-based account billing.

OBJECTIVES
- A reliable, low-latency redirect service for NFC and QR codes at scale
- Account holders manage devices, batches, and redirect destinations through a web dashboard
- A manufacturing workflow: generating large batches of devices with unique codes, and exporting print-ready QR images plus a manufacturer data file
- Monetization through tiered, subscription-based billing per account, with a choice of payment gateway
- Full ownership of the finished product transfers to us, including complete source code and all IP - no proprietary lock-in to the development team or their tooling

HOW IT WORKS
Each physical card we issue -NFC, QR, or both - is linked to a specific code generated by the platform. When someone scans the QR code or taps the NFC card, they're redirected using the link currently attached to that code. The card itself never changes; what it redirects to can be updated at any time from the dashboard. This is the core mechanism the rest of the requirements are built around. A card is inert until its owner activates it themselves, using a separate activation code provided at signup (see Self-Service Onboarding below).

SCALE & PERFORMANCE TARGETS
- Full-scale target: upwards of 1M+ active devices in production, handling millions of redirect requests per month
- Fine to launch small - early usage will be modest - but the architecture must not impose a hard ceiling that forces a rebuild later. Growth from a few hundred devices to a million should be a matter of scaling infrastructure, not rewriting the system
- Redirect responses must be fast and resilient - a cache-first architecture with a durable, consistent fallback

CORE FEATURE SET

Device & redirect management
- Every device (NFC card and/or QR code) has a permanent public identifier and URL that never changes
- Account holders can repoint a device's destination at any time without reprinting or reissuing it
- Redirect requests are served from a fast in-memory cache, with a durable database as the fallback of record
- The redirect path itself is minimal and stateless - no login/session overhead on the actual redirect, to keep it fast at scale
- Right after a scan/tap, before landing on the destination, briefly flash a small animated version of our product logo (asset to be provided separately) - just long enough to register visually, on the order of a second, then automatically continue on to the destination. This should stay a lightweight animation, not turn the redirect into a heavy page load

Self-service onboarding & activation
- A card ships in an inactive state - scanning or tapping it before activation redirects to a simple signup/activation page, not a broken or dead redirect
- The end customer (the business owner who received the card) signs up on the portal entirely by themselves - no manual account setup or provisioning from us
- During signup, they enter a unique activation code tied to their specific physical card (generated by the platform and shared with them separately, outside the code embedded in the QR/NFC itself). Entering the correct code is what turns the card live; without it, the card stays inactive indefinitely
- The whole flow - creating an account, adding an email and phone number, activating the card, and setting up a payment method -needs to be simple enough for a non-technical person to complete unassisted in a few minutes. No support call, no manual step on our side
- Payment setup should support direct debit / autopay, so the subscription renews automatically once configured
- Activation is a one-time step for the account holder only. Once a card is activated, every subsequent scan/tap - by the general public or whoever the card is meant for - redirects straight to whatever destination the account holder has configured (a review page, a menu, a link, etc.), depending on the use case. End users never see the signup/activation page

Dynamic QR & NFC codes
- The platform issues both NFC card identifiers and dynamic QR codes, sharing the same underlying permanent-ID system
- Codes/identifiers must be guaranteed globally unique, enforced at the database level

Manufacturing / batch generation
- Ability to generate large batches of devices (QR codes and/or NFC identifiers) in bulk, for physical manufacturing runs
- Batches above a configurable size threshold require an explicit confirmation step before generation, to prevent costly mistakes
- Batch export produces print-ready QR image files and a manufacturer data file (CSV, XLSX, or similar) containing the codes - this file is the only place the underlying plaintext codes are ever written to disk, and needs to be handled and encrypted accordingly
- Batch generation and export run as background jobs, not blocking the web application, since a single batch can contain many thousands of devices

Accounts, billing & subscriptions
- Each account subscribes to a tiered plan (multiple pricing tiers, e.g. by device-count limits or feature access)
- Billing supports multiple payment gateways - Stripe, PayPal, Razorpay, and others - with the account holder choosing their preferred option at signup/checkout rather than being locked to one processor
- Recurring billing, plan changes/upgrades, and payment-failure handling via webhooks, handled consistently across gateways
- Feature and usage limits enforced based on the account's current subscription tier
- Bulk email: notifications, promotional messages, and automatic payment reminders that go out only if a due payment hasn't actually been collected yet

Reviews / admin functionality
- Devices can direct end users to a range of destinations - a custom link, a fleet-management portal, a social media post, a Google Business review page, and similar
- The platform must never auto-post or fabricate reviews on a user's behalf -it may only direct a real person to go leave one

NON-NEGOTIABLE TECHNICAL REQUIREMENTS
- Every device/code gets a permanent public identifier and a clean, human-readable public URL
- Redirect lookups are cache-first (in-memory), with a persistent database as the fallback of record
- No raw end-user IP addresses are stored
- Redirect targets are validated server-side to prevent open-redirect vulnerabilities
- Codes/identifiers are enforced unique at the database level, not just in application code
- No hardcoded domain names in the codebase - the domain is configuration, not baked into the code, so it can be moved or rebranded later without a rewrite (this is about deployment flexibility, not per-customer white-label domains, which is out of scope unless discussed separately)
- All authorization checks go through a proper policy/permission layer, not ad hoc checks scattered through the code
- Full ownership of the finished project - including complete, unencumbered source code and all IP - transfers to us. No component should be built in a way that locks us into the development team or a proprietary tool we can't take over ourselves
- A mutual NDA will be signed before deeper implementation details or current build status are discussed

RATE LIMITING & ABUSE PROTECTION
- The redirect endpoint is the highest-traffic surface and needs layered rate limiting: coarse limits at the reverse proxy (Nginx) to absorb traffic spikes/DDoS-style floods before they reach the app, plus finer-grained, per-code and per-IP throttling at the application layer to catch abuse a blunt proxy-level limit would miss (e.g. one code being hammered far beyond normal scan volume)
- Signup, login, and activation-code entry must be rate-limited and back off on repeated failures - an activation code is effectively a credential that unlocks a physical device, so it needs protection against brute-force guessing in addition to having sufficient length/entropy
- Any bot-mitigation on the public signup/activation form should stay lightweight (rate- and behavior-based, not a heavy CAPTCHA) so it doesn't conflict with the "non-technical person, unassisted, a few minutes" requirement above
- Webhook endpoints need replay protection in addition to the signature verification and idempotency already listed - a request reusing a previously-seen event ID should be rejected, not reprocessed
- Batch-generation requests should also be rate-limited/quota-checked, not just gated by the confirmation-above-threshold step, so the background job queue can't be flooded by repeated large batch requests
- Rate limiting works by keying off the request's IP for a short-lived counter (e.g. in Redis, with a TTL of seconds to minutes) - this is compatible with the "no raw end-user IP storage" requirement as long as the IP itself isn't persisted or logged once the counter expires; it should never be written to a durable log or database table

GENERAL SECURITY HARDENING
- TLS everywhere, with standard security headers (HSTS, a real Content-Security-Policy, X-Frame-Options) on every non-redirect page
- Secrets (API keys, gateway credentials, DB passwords) via environment configuration, never committed to the repo
- Dependency/package vulnerability scanning as part of the build process
- Least-privilege database credentials for the application (no superuser-equivalent DB access from the web app)
- Encrypted backups, especially for the manufacturer export files noted above, which are the one place plaintext codes ever touch disk
- Please describe your standard approach to security hardening, confirm it covers the above, and flag anything you'd add that isn't listed here

HOSTING & RECURRING COST
Keeping recurring infrastructure/hosting cost low is a real priority, not a nice-to-have - this is self-funded, and we want to avoid a platform that's expensive to keep running.
- At launch, with a small number of users, hosting cost should be minimal - this should not require expensive infrastructure just to get started
- As the platform grows toward the 1M+ device scale above, some real infrastructure cost is unavoidable, but the architecture should default to cost-efficient choices (efficient caching, avoiding unnecessary managed-service overhead) rather than assuming an unlimited budget
- We'd like the proposed architecture to be transparent about where the ongoing cost comes from, so we can make informed tradeoffs as we scale

TECHNOLOGY STACK
- Backend framework: Laravel (PHP)
- Database: PostgreSQL
- Cache / queue layer: Redis
- Deployment: Docker Compose, with Nginx as reverse proxy / web server
- Frontend: server-rendered views (Blade) with Alpine.js for interactivity - no separate SPA framework
- Payments / subscriptions: multi-gateway (Stripe, PayPal, Razorpay, and others), selectable by the account holder - the payment layer should be built as an abstraction so more gateways can be added later without a rework

CURRENT STATUS
Not disclosed at this stage - happy to go into this once a mutual NDA is in place.

WHAT WE NEED IN YOUR PROPOSAL
- A cost estimate broken down by major project phase or milestone - not just one lump sum
- Your estimated timeline to delivery, and how you'd sequence the work.
- The makeup and experience of the team who would work on this - specifically experience with Laravel, PostgreSQL/Redis at scale, and multi-gateway payment integrations
- Your approach to testing and quality assurance
- Post-launch support and maintenance terms - we will need ongoing support after the initial build.
- Your proposed payment milestones/schedule
- Written confirmation that full source code and IP ownership transfers to us on delivery/payment, with any exceptions (e.g. third-party licensed components) called out explicitly
- Your prior experience with subscription billing across multiple payment gateways and webhook handling
- An estimate of monthly hosting/infrastructure cost at a few different points of scale - e.g. at launch, at 1,000+ devices, at 10,000 devices, and at 1M+ devices
- Whether you're open to a small, paid trial task (e.g. the redirect-lookup-with-caching piece) before committing to the full scope

PROCESS
- We'll sign a mutual NDA before we begin
- Milestone-based engagement preferred - each phase tested and accepted before moving to the next
- Please keep all communication through Upwork messaging at this stage

A client is looking for building a sales platform and we're looking for several developers. 3 backend and 3 frontends. Stack needed (You don't need to know them all) because some others devs might have them.
- NodeJS, PHP, Laravel, C#
- React, Vue, Angular
The stack is still undecided as it will be selected from the candiates that have more experience.

It's ok to use AI to develop, in fact we would prefer it as this project will flow more smoothly in terms of timing if AI is used.

Please apply if you have had experience creating sale platforms and similar websites. This project involves handling carts, stock, back orders and suppliers, as well as a section for handling bids, so it's important that you can design solutions to handle high traffic.

For better and faster delivery, we will use a tool called www.autodevtool.com that will be used for automating the design, backend and frontend development so the candidates can spend more time planning and refining requierments. so It's important that the candidates have experience with this tool.

When replying include if you have experience using the tool and how much time you've been using this tool, 1, 2 or 3 years.

Laravel Developer Needed for Existing POS Application — Long-Term Support

We are a small established business looking for an experienced Laravel developer to take over the ongoing support and development of an existing custom POS/business management application.

The application is currently running in production and is used every day at two business locations.

This is NOT a new application build. We need someone who is comfortable taking over an application developed by someone else, learning the existing code, troubleshooting problems, and making ongoing improvements.

Immediate Need

We are preparing to move from our current managed VPS host to a new managed VPS.

The hosting company will handle most of the server migration. We need a Laravel developer to:

Review the existing application before the move
Document its important server/application requirements
Help monitor the migration
Test the application on the new server
Identify and resolve any application problems caused by the migration
Make sure databases, email, scheduled tasks and other important functions are working properly
Longer-Term

After the migration, we want the same developer to provide ongoing support for the application, including:

Bug fixes and troubleshooting
Small feature additions and improvements
Database work
User-interface changes
Laravel/PHP updates when appropriate
Occasional urgent support when the application has a problem

I am the business owner, not a programmer. I can explain exactly how the application should work and test changes from the user's perspective. I need the developer to handle the technical side and communicate issues clearly.

We are looking for an individual developer rather than an agency and would like this to become a long-term relationship.

Required Experience

Strong experience with:

Laravel / PHP
MySQL or MariaDB
Existing Laravel applications
Linux VPS environments
cPanel/WHM
DNS and SSL
Server migrations
Git/version control

When applying, please briefly tell me:

How many years have you worked with Laravel?
Have you taken over an existing Laravel application written by another developer?
Have you helped migrate a Laravel application between servers?
Are you available occasionally for urgent evening or weekend problems?
What is your hourly rate?

Please start your response with "Pet Keeper" so I know you read the posting.

We will start with a small paid assignment before providing full access to the production system.

To look over my app code and help me submit to the apple developer website.

We are seeking an experienced full-stack developer to continue the iterative development, stabilization, and production readiness of an existing proprietary software platform.

The platform is already under active development. This next phase will focus on refining existing workflows, correcting inconsistencies, strengthening system reliability, improving the user experience, supporting third-party integrations, and preparing the product for controlled user adoption.

Responsibilities may include:

* Continue development and refinement of the existing web application
* Diagnose and resolve workflow, state-management, and user-interface issues
* Improve consistency across multiple user roles and portal experiences
* Build and maintain API and third-party service integrations
* Support document processing and AI-assisted platform functionality
* Perform testing, debugging, deployment, and production-readiness work
* Improve application performance, reliability, security, and cloud-cost efficiency
* Collaborate directly with the product owner through an iterative development and feedback process
* Maintain the confidentiality of all product architecture, business logic, documentation, and intellectual property

The ideal developer is comfortable working within an established codebase, translating detailed product feedback into dependable implementation, and balancing rapid iteration with long-term maintainability.

This is an ongoing engagement for an existing development relationship. Additional product and technical details will be provided privately as required for the work.

Relevant skills:

Full-Stack Development, React, Node.js, Python, JavaScript, Web Application Development, API Development, API Integration, Web Design, MySQL, HTML, CSS, Laravel, Vue.js, PHP

Senior Software Engineer (PHP/Laravel)
Location: Remote Eastern Europe (Contractor)
Engagement: 40 hours per week, ongoing contract

About Us:
We're a growing SaaS company building modern, scalable software that solves real problems for Field Service Management businesses across HVAC, electrical, plumbing, and adjacent trades. Our platform runs primarily on Laravel today, and we're actively investing in a strategic rebuild onto a TypeScript stack (NestJS). That means this role sits at both ends of the migration: shipping and hardening the current platform now, and helping build its replacement as the rebuild ramps.

We're looking for a senior engineer who can take full ownership of complex features end to end, raise the bar for the people around them, and help us scale. The team is worldwide, so you'll need to be flexible with working hours and time zones.

Responsibilities:
- Own features end to end: scoping, architecture, implementation, testing, rollout, and production support, across backend and frontend
- Architect and maintain robust, scalable backend systems in Laravel / PHP 8+, and contribute to the NestJS / TypeScript rebuild as it grows
- Partner with product and design to turn ambiguous problems into shipped features
- Optimize performance and lead the response on production issues
- Set technical direction through code reviews, design input, and mentorship of mid-level engineers
- Integrate third-party APIs and build the frontend surfaces your features need
- Write clean, testable, well-documented code across the stack
- Help evolve our engineering practices, tooling, and workflows

Qualifications
- 5+ years of professional software engineering experience, operating at a senior level
- Deep PHP 8+ and Laravel experience, including OO design, SOLID, and modern best practices
- Strong TypeScript and Node.js experience

- RESTful API design and authentication (OAuth, JWT)
- Solid automated testing discipline (PHPUnit, Pest, and TS equivalents such as Jest or Vitest)
- Comfortable in a Git-based, CI/CD environment
- Track record of working independently with minimal supervision and owning outcomes, not just tasks
- Strong written and verbal communication across a distributed team

Nice To Have:
- NestJS specifically (Laravel experience transfers conceptually)
- Microservices or modular monolith experience
- Docker, Kubernetes, and AWS
- A modern frontend framework (React or Vue)
- Prior SaaS startup experience

Hey if you're someone who genuinely enjoys owning infrastructure and solving real production problems, this might be a good fit.

We're BikeFixUp, a tech-driven two-wheeler service startup based in India. We're small, we move fast, and we're looking for a DevOps engineer we can actually trust with our production environment not just someone to restart services when things break.

What you'll be working with:
Ubuntu VPS · Caddy · Cloudflare · PostgreSQL · Redis · Laravel/PHP backend · Multiple live projects

What the role actually involves:

Keeping our servers hardened, patched and monitored
Managing Caddy routing, Cloudflare DNS/SSL and firewall rules
Deploying applications, handling rollbacks, managing queues and workers
Owning database health PostgreSQL primarily, some MySQL and Redis
Troubleshooting beyond the server app config, runtime errors, connectivity, permissions
Maintaining a clean infrastructure runbook so nothing lives only in one person's head
Responding to critical incidents when they matter most
Proactive monitoring catching issues before they become outages

You're probably a good fit if:

You have 4+ years of hands-on Linux/DevOps experience in production environments
PostgreSQL isn't scary backups, restores, permissions, performance
You've worked with Caddy or Nginx, Cloudflare and Redis before
You can explain a real incident you diagnosed and fixed root cause and all
You're comfortable with a long-term, stable retainer arrangement
You can respond to critical issues promptly when needed

What we're offering:

$35/month fixed retainer this is a startup budget and we're upfront about it
Direct access to the founding team no middlemen, no ticket queues
Real ownership of a live production environment across multiple projects
A stable, long-term engagement if the relationship works well
Honest communication and genuine respect for your expertise

A few practical notes:

An NDA is required before production access is granted
We follow least-privilege access you'll have what you need, nothing unnecessary
Docker may be used case-by-case where it makes sense

To apply, start your message with: TRUSTED DEVOPS

Then tell us:

Your years of DevOps/Linux experience
Your familiarity with our stack (Ubuntu, PostgreSQL, Redis, Caddy/Nginx, Cloudflare)
One real production incident you diagnosed and resolved
Your backup and disaster recovery experience
Your typical response time for critical incidents
Confirmation you're okay signing an NDA

We're not looking for a vendor. We're looking for a technical partner who wants to grow with us.

Bonus (not required): Familiarity with PHP / Laravel — our main project runs on it, so if you've worked with it before, that's a plus when troubleshooting application-level issues.

Job Description
We’re looking for an experienced Full-Stack Developer to improve an existing web application by adding a new feature and making a few related updates.
You’ll work with the existing codebase, understand the current functionality, implement the requested changes, and ensure everything works smoothly without breaking existing features.

Deliver clean and maintainable code


Required Skills

React.js
Node.js / Laravel / PHP
JavaScript / TypeScript
REST APIs
MySQL / MongoDB
Git
Full-Stack Development
Responsive Web Development


Deliverables

Fully implemented feature
Frontend and backend updates
Working API/database integration
Bug-free tested functionality
Clean, production-ready code


We’re looking for someone who can start immediately and complete the task within 1–2 days.

We are looking for a Laravel developer to help build and maintain web applications for our business. The ideal candidate should be comfortable working on backend development, database integration, and improving application performance. You will collaborate with our team to deliver reliable, scalable solutions and support ongoing updates and improvements. Experience with similar projects and strong communication are important for success in this role.

Clear Expectations & Deliverables

Project Scope & Architecture: Defining technical requirements, features, and database architecture for both web and mobile platforms upfront to prevent scope creep.

Core Deliverables: Clean, maintainable codebase, fully responsive websites, testable mobile builds (APK/TestFlight), and comprehensive technical/API documentation.

Milestones & Deployment: Clear sprint timelines covering design integration, development, quality testing, and final deployment to web servers and app stores (App Store & Google Play).

Required Technical Skills

Full-Stack & Cross-Platform Development: Proficiency in modern web and mobile frameworks (e.g., React, Vue, Node.js, Flutter, Laravel, Kotlin/Swift) to build high-performance applications.

Responsive Design & Performance Optimization: Ensuring seamless user experience across all screen sizes and browsers, with optimized load times and efficient resource management.

APIs, Security & Data Management: Secure database integration, robust REST/GraphQL API integration, data encryption, and third-party service connections (e.g., payment gateways).

Effective Communication

Progress Transparency: Providing regular updates on completed features, upcoming milestones, and sprint progress.

Proactive Problem-Solving: Flagging technical blockers or infrastructure risks early alongside practical solutions and alternatives.

Structured Channels: Utilizing project management and communication tools (e.g., Jira, Trello, Slack, GitHub) to keep discussions, code reviews, and feedback organized.

Working Style & Dynamics

Agile & Iterative Process: Developing projects in iterative cycles, delivering functional previews early for continuous testing and feedback.

Rigorous Testing & QA: Conducting cross-browser and cross-device testing to ensure bug-free releases and high performance before public deployment.

Technical Ownership: Exercising strong problem-solving independence while choosing the optimal tools and architecture to meet product goals effectively.

Job: Full technical build-out for an autonomous dropshipping store (Shopify + n8n + supporting agents)

Context: I'm building an automated dropshipping business — custom Python agents (via GitHub Actions) handle inventory, marketing, and finance, reading/writing to Shopify. I'm not operating this stack day-to-day myself and want someone who can own the technical build end-to-end.

What I'll handle: store account, GitHub repo access, and product/pricing decisions — I'll provision access and stay the approver on anything business-facing.

What I need from you:

Redevelop GitHub Actions automation to get it running again
Set up a custom Shopify app with API credentials, and an n8n instance to sit between Shopify and my agents
Build whatever webhooks/automations are needed to connect Shopify events (orders, inventory, fulfilment) through to my systems reliably — no fragile tunnelling
Connect DSers (or CJ Dropshipping) for supplier fulfilment
Extend my existing supplier agent past its current verify-only state
Build a lightweight video generation pipeline (fal.ai/Seedance) for marketing content
Build out the one remaining compliance agent in my stack

I have existing agent code and infrastructure already built — this is extending/fixing/connecting it, not starting from zero.

Payment: contingent on a working outcome — the store takes a real order and it flows through fulfilment and my agent systems end-to-end, with TikTok Shop and the supplier integration live. Open to a fixed-price or milestone structure on that basis.

How long would you estimate, and what access do you need from me to start?

I need strong developer who has knowledge on building web and mobile apps

We are looking for an experienced and reliable Full-Stack Developer to join our project and help us build, improve, and maintain a modern, scalable web application.

The ideal developer should be comfortable working on both frontend and backend development, integrating APIs, managing databases, fixing bugs, and building clean, responsive user interfaces

I am not looking for a simple brochure website. The current site has been built by Hostinger's AI backend and it's awful as you can see. It is not possible to alter it outside of the Hostinger environment and I will need full control to adapt images and text myself, which Hostinger does not allow. So I need a complete new site with a proper membership/user-account system, protected members-only content and an easy-to-manage backend.

I'd like you to review the websites and provide a proposal for building a similar site with family camping club branding, content and design.

### Main requirements

The website needs to include:

* A professional, modern and mobile-responsive design
* Public-facing pages that anyone can access
* A member signup/registration system
* Member login/logout
* Forgotten password/password reset functionality
* Secure member accounts
* A members-only area
* Pages/content that are only accessible to logged-in members
* The ability for me to add, edit and remove members-only pages/content
* The ability to add new members-only sections in the future
* An administrator/backend area where I can manage the website and members
* A database for securely storing member/account information
* Email notifications for registration, password resets and other relevant account actions
* The ability to add HTML content to pages when required

### Content management

I need to be able to manage the website myself after it has been built.

Ideally, I should be able to:

* Create new pages
* Edit existing pages
* Edit text and headings
* Upload/change images
* Add HTML
* Add links
* Create members-only content
* Move or reorganise content
* Manage adverts
* Manage members
* Make changes without having to ask a developer every time

Please explain what CMS/backend you recommend and why.

### Advertising

The website will generate revenue from advertising, so I need properly designed advertising areas throughout the site.

I need the developer to build flexible advert slots where I can later add:

* Image adverts
* HTML adverts
* JavaScript advert code
* Google advertising/AdSense or similar advertising systems
* Potentially different adverts in different areas of the website

The advert areas should be responsive and work correctly on desktop and mobile.

I'd also like the advert system to be flexible enough that I can change adverts without having to alter the site's underlying code.

### Members-only functionality

The members' area is particularly important.

I need proper access control so that protected content cannot simply be accessed by somebody who isn't logged in by guessing or copying a URL.

Please explain how you would implement authentication and protect members-only pages.

I'd also like the system to be capable of having different membership/access levels in the future if required.

### Security

Security is very important because the website will contain member information.

I need the site to follow good current web security practices, including:

* Secure password storage/hashing
* Secure authentication
* Protection against common web attacks
* Secure database practices
* HTTPS/SSL
* Secure admin access
* Appropriate session management
* Protection of members-only content
* Regular backups
* GDPR-conscious handling of personal information

Please explain your approach to website security and backups.

### Technical requirements

I'm looking for someone with proven experience in:

* Full-stack web development
* HTML5
* CSS
* JavaScript
* Backend development
* Database development
* CMS development
* Membership/user authentication systems
* Responsive/mobile development
* Website security
* SEO
* Website performance optimisation
* Hosting/deployment
* Analytics
* Advertising integrations

Experience with WordPress/custom CMS development is useful, but I'm open to your recommendation if you believe another technology would be more appropriate.

### SEO and performance

The website should be built with SEO and performance in mind.

I'd like:

* SEO-friendly URLs
* Editable page titles/meta descriptions
* Fast page loading
* Mobile optimisation
* Proper heading structure
* Image optimisation
* XML sitemap
* Google Search Console compatibility
* Google Analytics/GA4 integration
* Appropriate redirects and canonical URLs where required

### Ownership and handover

An important requirement is that I own the website and everything associated with it when the project is completed.

Please confirm that I will receive:

* Full ownership of the website
* Source code
* Database
* Website files
* Admin access
* Hosting access
* Domain/DNS access where applicable
* Any design/source files created specifically for the project

I don't want the website to be locked into your own proprietary system, I wish to have it hosted on a plan that I already have.

Please also explain what ongoing maintenance/support you offer after launch and your costs for this.

### Your experience

Please send me:

1. Examples of websites you have personally built
2. Examples specifically involving membership/login systems
3. Examples involving members-only/protected content
4. Examples where you have integrated advertising
5. Details of the technology/CMS you would recommend for this project
6. Your estimated development time
7. Your estimated cost
8. What is included in your quote
9. Your ongoing maintenance/support options and costs
10. Details of your hosting/deployment experience
11. Any additional costs I should be aware of

I'd particularly like to see live examples of websites where you have built the actual membership functionality yourself, rather than just general website design work.

I'm looking for a developer who can build this properly as a secure, scalable website that I can continue to manage and develop over time. I am looking for a developer that I can work with for years to come not just a one site and done.

Please review the websites before responding so that you understand the type of website and functionality I'm looking to replicate, while using our own branding, content and design.

Please let me know how you would approach the project and what technology/CMS you would recommend.

Many thanks for your time and consideration, I do hope that we can work together on this.

Kindest regards,
Ray

Job Description:
We run a curated social/dating matchmaking event brand. We already have the core mathematical matching algorithm written and fully tested in Python (⁠NetworkX⁠, TF-IDF NLP semantic scoring, and bipartite min-cost flow).
We now need a reliable full-stack developer to build the user registration portal, set up the database, connect our existing Python matching script, and configure automated match notifications.

Integrations between KlickTipp and other tools. Build scalable SaaS apps with React, Node & Next.js.

We run an existing e-commerce store built on Laravel 12 + Botble CMS (MySQL, Laravel Mix). The active theme is a child theme that inherits from a parent theme (Farmart-based). An approved redesign is ready in Figma: desktop and mobile, roughly 30 to 35 pages, fixed scope.

Our designer delivers the visual layer: first-pass Blade markup plus a Sass component library for shared elements (header, nav, mega menu, footer, product cards, tiles, banners, carousels, typography, buttons, forms) and static page mockups.

You own the implementation:

- Local environment setup from a sanitized database and representative media
- Integrating the supplied components and pages into the Botble theme structure (inheritance, asset and render hooks, Laravel Mix, shortcodes)
- Wiring redesigned pages to existing data and behavior: products, variations, stock, prices, specifications, category navigation, filters, sorting, search, pagination, cart, coupons, checkout, customer accounts, CMS editing controls, SEO metadata, URLs, analytics hooks
- Preserving existing custom ecommerce behavior implemented as service decorators in a custom plugin (product search and visibility, size filtering with unit conversion, variation handling, coupon restrictions, caching, schema)
- Refactoring one large product-detail template (long file, inline styles) against representative data
- Testing across desktop, tablet, mobile, and an agreed browser set, including checkout with test credentials
- Two consolidated revision rounds within the approved designs
- Coordinating the production release with our deployment owner, compiling and committing the required generated assets
- 1 or 2 new features,
- No backend logic changes, infrastructure work, content entry
- No changes to payment or shipping business logic.
- Connecting the redesigned UI to existing payment and shipping behavior is in scope.

We work in feature branches with review before merge. No direct commits to the main branch.

Must have
- 3+ years of production Laravel experience, confident debugging integration issues
- Shipped at least one custom CMS theme, ideally one that overrides a parent theme's ecommerce views
Blade, Sass, Laravel Mix or Webpack asset pipelines
- Git feature-branch workflow, comfortable working carefully against a production store
- Nice to have: Botble ecommerce plugin internals, GitHub Actions deploy pipelines.

Confirmation you're comfortable signing an NDA

Retainer Budget: $35/month (fixed) long-term engagement

We're a small startup with a limited budget but serious infrastructure needs. We're looking for someone who values trust, ownership, and a long-term working relationship over a high one-time payday.

We are planning a production-grade, multi-tenant property-management and payments SaaS built with Vue 3, a modular Laravel API, PostgreSQL, object storage, and managed cloud deployment. We are comparing a small number of full-service teams and agencies for the full build and would like a supportable fixed-price proposal rather than a generic pitch.

SCOPE

The scope includes authentication and social sign-in; strict organization isolation; roughly nine roles across owner, staff, tenant, and vendor portals; properties, units, owners, tenants, occupancy, move-out, leases, renewals, and signed-document workflows; Stripe Connect owner routing and rent collection; autopay, manual and partial payments, credits, refunds, subscriptions, late fees, recurring charges, collections, deposits, CAM, and an auditable double-entry ledger with idempotency and concurrency controls; insurance; maintenance requests, photos, vendor assignment, and a vendor portal; secure documents, templates, basic e-sign, retention, legal holds, records export, and cleanup; transactional email and SMS consent/status handling; dashboards, reports, CSVs, admin/support controls, onboarding, custom fields, feature flags, and settings; a public marketing/help/legal site; and CI/CD, monitoring, security controls, deployment, and automated tests.

INTEGRATIONS

Planned integrations are Stripe/Stripe Connect, Twilio, Mailgun, Turnstile, Google and Apple sign-in, Sentry, object storage, and a managed cloud host.

BREADTH

Approximately 50 user-facing workflows, 50 frontend routes, and 170 distinct API paths. This is a full production platform, not a thin MVP.

EXCLUSIONS

Native mobile apps, historical data migration, tenant application/screening, provider usage fees, formal legal/compliance advice, and certified e-signature-provider fees.

WHAT TO INCLUDE IN YOUR PROPOSAL

1. A fixed-price low/high range for the complete scope.
2. Your standard hourly or blended team rate for ongoing maintenance and feature work after launch.
3. A calendar timeline and proposed team composition, including approximate size and roles, and how much of each role is actually allocated over the timeline.
4. The assumptions, dependencies, and exclusions behind the range.
5. One comparable property-management, fintech/payments, marketplace, or multi-tenant SaaS project and what you delivered.

If paid discovery is necessary before a firm price, please price it separately and still provide the best full-build ballpark you can support today.

Proposals that only ask for a call, or give a single number with no assumptions, will not be shortlisted. Total hours across all roles should be consistent with the team size and timeline you propose.

We need a senior Laravel developer to secure and upgrade a live booking system that has been running since 2016.
The system takes real bookings and real payments every day. It runs on a self-managed DigitalOcean droplet. It is years out of date, it has been attacked before, and the developer who built it left no documentation.

Two things are happening here and both matter. The security work is urgent and starts in week one, on the live server, before the upgrade planning is finished. The upgrade follows it.
This is not a redesign. Every feature has to keep working: booking, admin, pricing, capacity, payments, PDF generation and email.

The stack today
• Laravel 5.2.41, PHP 7.0, MySQL
• Admin in Laravel Blade, jQuery and Bootstrap 3
• Customer booking frontend in AngularJS 1.5, compiled and served from public/booking
• Stripe and SagePay/Opayo, Excel export, wkhtmltopdf, Mailgun
• Ubuntu, Nginx, PHP-FPM 7.0, MySQL on a DigitalOcean droplet managed over SSH

What the work covers
Security first. Establish whether anything is still present from the previous compromise. Audit every credential. DigitalOcean Cloud Firewall, SSH hardening, Cloudflare with WAF. Logging with automated email alerts. Backups with a tested restore.
Server. Rebuild on current Ubuntu, Nginx, PHP 8.3 and current MySQL, with a password protected staging clone. You need real DigitalOcean and Linux VPS experience, not Laravel alone.
Laravel. 5.2 to 11 in stages, PHP 7.0 to 8.3, with the application working at the end of each stage. Laravel Shift or equivalent is fine, tell us if you plan to use it. Replace Bower, Gulp and Elixir, the old Excel library and anything else unmaintained.
Admin. Blade, jQuery and Bootstrap 3 working on the new stack. Functional fixes only, no redesign.
Integrations and testing. Stripe, Opayo, wkhtmltopdf, Excel export and Mailgun all retested. Automated smoke tests on the booking flow and both payment paths, because there are none today.

Handover.
A deployment runbook, an upgrade log and a security findings report, written for a developer who has never seen the system.
Not in scope
The AngularJS 1.5 booking frontend is not being rewritten. It must keep working on the new stack. We may fund that separately later, so mention it if you have done AngularJS to modern Angular work, but it is not a requirement.
How we work
Plan first, then work in stages. After every stage the live booking flow, admin and payments must still work. Fixed scope, with a documented scope of work covering 18 items and acceptance criteria. We share it with shortlisted applicants and ask you to estimate every item. Payment is in stages against working deliverables.
Who we want
Individual freelancers only. We are not looking for an agency, a studio, or a developer who will pass this to a team. If you are one person and this is your own work, we are interested wherever you are based.
Agencies: do not approach us by email, phone, LinkedIn or WhatsApp. Any approach outside Upwork will be ignored and reported to Upwork.
How to apply
Answer the questions below. Applications that do not answer them will not be read.
Shortlisted applicants are paid for a short review task before we commit to the full engagement. You get read access to the codebase and the server and give us a written upgrade plan, what you found, the three biggest risks, and your estimate against every item on the scope of work.

We’re looking for a Node.js developer to help us with some quick fixes and improvements on our existing web application.

The backend is built with Node.js, Express.js, PostgreSQL, and Redis. We currently have a few issues with API responses, payment webhook handling, and some backend logic that needs to be cleaned up.

We’re looking for someone who is comfortable working with an existing codebase and can quickly identify and fix issues without affecting the current functionality.

The work includes fixing several REST API endpoints, improving error handling, resolving a payment webhook issue, and making a few small PostgreSQL query improvements.

Experience with Node.js, JavaScript/TypeScript, Express.js, REST APIs, PostgreSQL, Redis, and third-party API integrations is important.

If everything goes well, we may also need help with additional backend functionality in the future.

MVP Scope:

Restaurant accounts
Supplier accounts
Admin dashboard
Product catalog
Order management
Order status tracking
Push notifications
Arabic & English support (RTL)
FlutterFlow + Supabase preferred
Restaurants should not see supplier contact details.
Multiple suppliers can provide the same product.
Admin should be able to manage suppliers, products, and orders from a web dashboard.
The MVP is intended for an initial launch with a small number of suppliers and restaurants to validate the business model.

Could you please share:

Similar projects you have built (Marketplace, B2B, Ordering System, POS, Multi-Vendor, E-commerce).
Your recommended tech stack.
Estimated timeline.
Fixed-price estimate.
Whether you can provide the complete source code / FlutterFlow project files upon delivery.
