Find Node.js Projects Faster on Upwork

We're looking for an experienced full-stack developer to build a custom CRM/SaaS-style system for our small business. We currently manage everything through spreadsheets and need to move to a proper, structured platform that can scale like a SaaS product over time.

What we need:
- A CRM with contact/lead management, pipeline stages, and basic reporting
- Built with a SaaS mindset — clean data structure, role-based access, and room to add features or additional users later
- Role-based access (admin vs. team member views)
- Integration with our existing email tool (we can share details)
- Clean, documented code — we want to be able to maintain this ourselves or hand it to another developer later

Ideal skills:
- React / Next.js (frontend)
- Node.js / Express.js (backend)
- PostgreSQL or MongoDB (database design)
- REST API development
- Experience building CRM or SaaS platforms specifically (not just generic websites)

Nice to have: Docker/CI-CD experience, prior work migrating a business off spreadsheets into a SaaS-style system.

Please include in your proposal: a similar CRM/SaaS project you've built (link if possible), your suggested tech approach, and an estimated timeline.

We need a reliable full stack developer to jump into an existing web application and resolve a small issue involving React, Node.js, and REST API data flow.

The application is already built, so this is not a greenfield project. You’ll review the relevant code, identify where the data flow is breaking, and implement a clean fix without disrupting the existing architecture or UI.
What You’ll Work On
Investigate the current React component and API flow
Identify and resolve the data handling issue
Ensure API responses are rendered correctly in the frontend
Review loading, error, and edge case handling
Modify the Node.js endpoint if the issue requires a backend adjustment
Preserve the existing UI, styling, and code structure
Test the change and confirm the feature works as expected

Current Stack:
- Frontend: React, JavaScript/TypeScript, HTML/CSS
- Backend: Node.js, REST APIs
- Tools: Git
Experience with Next.js, Express.js, Directus, or database integrations is helpful but not essential.

Ideal Developer:
We're looking for someone comfortable working with an existing codebase and debugging full stack issues involving:
- React and frontend development
- Node.js and backend development
- REST API integration
- JavaScript/TypeScript
- Data fetching and state handling
- Web application debugging
- Git

This should be a small, focused task for someone who can quickly understand an existing application, trace the issue, and deliver a clean, production-ready fix.

Budget: $50 fixed price

When applying, please briefly share your React/Node.js experience and mention one similar web application or API integration issue you've successfully resolved.

PRODUCT & DEVELOPER BLUEPRINT
Version 1 - Minimum Viable Product (MVP)
Core experience: FIND CONNECT MESSAGE MEET
Prepared for development estimates and MVP scoping

1. Concept & Purpose
TravelBud - Cannabis Connection is a location-based social meetup app for adults who enjoy cannabis and want to connect with like-minded people.
The app is intentionally simple. TravelBud provides the connection; users decide naturally what develops from it, including friendship, conversation, activities, travel connections, and other personal relationships.
FIND CONNECT MESSAGE MEET
TravelBud also connects members with licensed dispensaries, including participating TravelBud Partner dispensaries that may offer exclusive member discounts or promotions.
2. Core App Experience - The Active Map
The map is the primary TravelBud experience. After registration, users should be able to open the app and quickly understand who and what is around them.
• TravelBud Members - users who have chosen to be visible on the map.
• Looking to Smoke - an optional temporary status showing interest in meeting for a smoke meetup.
• Hosting a Smoke - an optional temporary status showing openness to hosting a smoke meetup.
• Dispensaries - licensed dispensary locations shown with a distinct map icon.
• TravelBud Partner Dispensaries - participating dispensaries receive a recognizable partner/discount indicator.
A user taps a member on the map, views a basic profile, and sends a connection request. Once accepted, private messaging becomes available. No swipe-based or complicated matching system is required for the MVP.
3. Registration & Member Profiles
• Account registration and login.
• Profile photo.
• First name or display name.
• Age.
• Short biography.
• General location.
• Optional interests.
• Current smoke-meetup status.
• Map visibility control.
• Connect button.
Privacy requirement: precise private location should not automatically be revealed to other users. Map/location implementation should be designed with member safety and privacy in mind.
4. Smoke Meetup Status
Users may optionally activate one of two simple, temporary statuses:
• Looking to Smoke
• Hosting a Smoke
Statuses should be easy to turn on and off. They are intended to communicate current social availability rather than become permanent profile categories.
5. Connections & Private Messaging
The MVP connection flow should remain intentionally simple:
Tap Profile Connect Request Accept Private Message Meet
• Send connection request.
• Accept or decline request.
• Private messaging after acceptance.
• Disconnect.
• Block.
• Report inappropriate behavior.
6. Dispensaries & TravelBud Partner Offers
Licensed dispensaries appear on the active map. Participating businesses can be identified with a TravelBud Partner icon or badge.
Tapping a participating dispensary should display its current TravelBud member offer or discount and basic dispensary information.
Example member-facing message: "One dispensary visit could pay for your entire year."
The initial partnership model can remain simple: participating dispensaries provide a member benefit in exchange for exposure to the TravelBud community. More advanced paid advertising, featured placement, sponsored promotions, and redemption analytics can be considered after the user base grows.
7. Digital TravelBud Member Pass
Every active paid subscriber should receive an in-app digital TravelBud Member Pass.
• Clearly displays ACTIVE MEMBER status.
• Can display first name/profile photo and membership validity.
• Allows participating dispensary staff to visually verify membership for the MVP.
• Architecture should allow rotating QR-code verification/redemption to be added later.
The MVP does not require point-of-sale integration.
8. Membership & Subscription
Current proposed launch membership: $14.99 per year.
Version 1 should use a single, simple membership rather than multiple pricing tiers. The developer quote should include implementation of the annual in-app subscription/payment flow appropriate for iOS and Android, including restoration and active-membership status.
9. Travel Mode
TravelBud should be designed so a user can explore another location on the map, allowing travelers to discover members and participating dispensaries before arriving.
If including full Travel Mode materially increases MVP cost or complexity, the developer should price it separately as an optional feature rather than silently expanding the base MVP.
10. Founding 500 Launch Concept
TravelBud's initial launch strategy is to create a concentrated first community rather than spreading a small number of users nationwide.
Working campaign: The TravelBud Founding 500.
The first 500 members will provide real-world feedback about which additional features should be prioritized after the MVP.
11. Product Boundaries for Version 1
TravelBud is a social connection platform. The MVP should not be designed as a private cannabis marketplace or transaction system.
The initial product should not include user-to-user product listings, cannabis ordering, cannabis payment processing, or delivery coordination.
Appropriate terms, community guidelines, reporting tools, age/access requirements, and dispensary promotion rules will be finalized with legal review before public launch.
12. MVP Philosophy - Do Not Overbuild
The development goal is a clean, reliable first version centered on:
ACTIVE MAP STATUS DISCOVER CONNECT MESSAGE MEET
Plus:
DISPENSARIES PARTNER OFFERS MEMBER PASS
Do not add dating modes, complex matching algorithms, social feeds, ratings, gamification, extensive meetup categories, or other major features to the base MVP unless specifically approved.
13. Developer Quote Request
Please base your quote specifically on the MVP described in this document. Price additional or recommended features separately.
• Fixed-price estimate for the complete MVP.
• Estimated development timeline.
• Recommended technology/platform and the reason for the recommendation.
• Clear list of what is included and excluded.
• Backend, database, mapping, messaging, authentication, subscription, and hosting assumptions.
• Apple App Store and Google Play submission/launch support.
• Expected ongoing hosting, third-party service, and maintenance costs after launch.
• Testing, bug-fix, and post-launch support period included in the quote.
• Confirmation of how source-code repositories, cloud accounts, app-store accounts, and third-party service accounts will be structured and handed over.
• Confirmation that all custom source code, designs, and project intellectual property created for TravelBud will be owned by the client upon payment, subject to the final development agreement.
• Any features in this blueprint that the developer recommends postponing from Version 1, with separate pricing.
14. One-Sentence Product Description
Open the map. See who's around. Find someone who wants to smoke or host. Connect and meet. Discover nearby dispensaries and TravelBud member deals.
TravelBud - Cannabis Connection | Developer Blueprint | MVP

I’m working on a small logistics MVP and need a full-stack developer to help build the first version.

Web platform where users can add shipment details, compare a few delivery options, and see which one makes the most sense based on total cost and delivery time.
The platform should calculate the actual cost, including extra fees, and use AI to recommend the best option.

For the first version, I’m thinking:
-React dashboard
-Node.js backend
-SQL database
-Shipment and order management
-Compare a few delivery providers
-Cost and fee calculations
-AI recommendation
-Basic dashboard with key stats

There’s a small financial side as well. We need to include transaction fees and additional charges so the user can see the real cost, not just the shipping price.
For the AI I don’t need anything complicated. An AI API working with the shipment data is enough. The main goal is to make a useful recommendation based on cost, delivery time and fees.
React, JavaScript, Node.js, SQL and AI experience would be a good fit. Python can be used where it makes sense. Git and clean Software Architecture & Design are important too.

I want to keep the first version small and practical. No big integrations or over-engineering. Just a clean MVP that works and gives us something to build on later.

How would you approach the AI recommendation part without making the first version unnecessarily complicated?
Send me your approach and a couple of relevant projects you’ve worked on.

We’re looking for a Full Stack AI Engineer to help build a Generative AI SaaS Platform.
You’ll work across frontend and backend development, LLM integrations, AI workflows, RAG, vector databases, and API integrations.

Requirements:
Full-stack development with React/Next.js and Python/Node.js
Experience with Generative AI and LLM APIs
RAG, embeddings, and vector databases
SaaS and API development experience

Please share relevant AI projects you’ve built.

Looking for an experienced Solana developer to build a **custom private copy-trading bot**, similar in concept to Bloom Bot but built specifically for me. The bot should monitor selected Solana wallets and automatically copy their trades with a strong focus on **fast transaction detection and execution**. that guarantees no tx between me and target wallet.

Important Notice to Applicants:

Please note that we are only contacting and communicating with candidates through Upwork. Any applications or direct contact made outside of these channels, including emails, social media messages, direct messages to our CEO, or messages sent to our general company email, will not be considered and will be automatically declined.

About the Company:

We are a private U.S.-based company operating across multiple departments that support legal, staffing, and client-service operations. Our teams collaborate in dynamic, fast-paced environments focused on innovation, integrity, and client success.

In this role, you’ll work closely with leadership and cross-functional teams, making a real impact in operational, legal, and client-focused projects—all from the comfort of your home. Details about our company structure and associated teams will be introduced during the interview process.

About the Role:

We are building an AI-enabled intake and conversion platform for law firms. Our human and AI agents engage prospective clients, complete intake workflows, and help firms convert qualified prospects into signed clients.

That only works if information moves reliably between our platform, our clients' systems, and the partners that supply leads. You will design and build that integration platform — production APIs, event-driven services, and CRM connectors — leading technical discovery yourself and turning recurring requirements into reusable capabilities rather than one-off scripts.

What You Will Build:

Client APIs and Event Delivery

Build secure, documented APIs and a reliable webhook platform that deliver intake, lead, and conversion outcomes to client systems.

Own delivery mechanics and API standards: subscriptions, authentication, webhook signing, retries, idempotency, replay, versioning, and the documentation and testing tools customers need to self-serve.

Inbound Lead and Partner Integrations

Build services that securely accept leads and potential cases from external vendors on behalf of hundreds of law-firm clients, built on a canonical intake model and an adapter framework that normalizes new partners without duplicating core logic.

Handle validation, deduplication, attribution, consent and source tracking, and tenant routing, and build monitoring and reconciliation tools that make missing or misrouted leads visible and recoverable.

CRM Connectors and Custom Client Work

Turn recurring client requirements into reusable, configurable connectors — installable packages, managed integrations, and embedded workflows — with secure OAuth or API-key onboarding.

Design configurable field mapping, routing rules, and synchronization behavior so a new firm can be connected without an engineer, and own connector deployment, versioning, and support.

Lead technical discovery with law firms, CRM administrators, and vendors; deliver custom integrations as paid engagements when a connector is not appropriate; and fold reusable components back into the platform.

Platform, Reliability, and Security:

Design multi-tenant, event-driven services with strong isolation of customer data and credentials, and own them from design through deployment, monitoring, and incident response.

Design for third-party rate limits, outages, schema changes, and duplicate events, backed by structured observability, automated contract and integration testing, and replay tools.

Protect sensitive lead, caller, and case data through least-privilege access, secure secret storage, credential rotation, tenant-aware authorization, and configurable retention.


Required Experience:

Typically 5 or more years of software engineering experience, including ownership of backend, platform, or integration systems.

Hands-on experience designing and operating customer-facing APIs, webhooks, or integration platforms in production.

Strong proficiency in a modern backend language (TypeScript/Node.js, Python, Java, Go, or C#) plus strong SQL and relational data modeling.

Deep understanding of event-driven systems, distributed-system failure modes, and API authentication patterns including OAuth 2.0, API keys, JWTs, and signed requests.

Experience designing reliable integration behavior — retries, idempotency, rate limiting, replay, reconciliation, and schema evolution — backed by automated contract and integration testing.

Experience with multi-tenant SaaS and operating services in AWS, Azure, or GCP using containers, CI/CD, and infrastructure as code.

Experience working directly with customers and partners on discovery and launch, translating messy business processes into maintainable software, and a self-directed approach to ambiguous problems.

Preferred Experience:

Integrations with CRM, case-management, or lead-management platforms such as Salesforce, Litify, HubSpot, Filevine, Clio, or Lawmatics.

Salesforce work involving Apex, REST APIs, Platform Events, Flow, or managed packages, or publishing installable apps, marketplace connectors, or SDKs.

Legal technology, law-firm operations, legal intake, or professional-services delivery, including billable client engagements.

SFTP, batch imports, change-data capture, or streaming platforms, and familiarity with MCP or secure data interfaces for AI agents.

Depth in one or two platforms, plus the ability to learn unfamiliar APIs and data models quickly, matters more than familiarity with all of them.

What Success Looks Like:

Clients and partners exchange standardized outcomes and leads through reliable, documented interfaces instead of manual work.

Integration failures are visible, diagnosable, and recoverable.

New vendors and CRM systems are added through reusable adapters and configuration, so onboarding each new client, CRM, or lead source takes less time.

This project centres on delivering a full-stack, professional-grade portfolio site that presents my work and credentials with the clarity and authority expected in a corporate setting. The front end must feel sleek and trustworthy; the back end needs to give me a straightforward way to add projects, update copy, and manage imagery without touching code.

Visual direction is clean typography, restrained colour use, and subtle interactive cues that support, rather than distract from, the content. Pages must load quickly, adapt flawlessly to desktop and mobile screens, meet basic accessibility guidelines, and ship with on-page SEO best practices already in place.

Any modern stack you are confident supporting is acceptable—React/Next.js with Node, Vue/Nuxt, or Laravel are typical examples—as long as it delivers performance, security, and an SEO-friendly architecture. Explain your choice and how it fits the brief.

Acceptance criteria
• Home, About, Work/Projects, and Contact pages complete and editable via CMS or markdown
• 90 + Google Lighthouse scores on desktop and mobile
• Code pushed to a private Git repository and deployed to my hosting with basic CI/CD
• Source files, database (if used), and clear setup instructions provided at hand-over

Include a concise timeline broken into milestones and links to comparable corporate portfolios you have shipped so I can gauge fit.

Skills: PHP, Website Design, Graphic Design, SEO, HTML, Node.js, React.js, Full Stack Development

This is a full-time, two-year contract to design, build, and maintain a production-grade MERN application from the ground up. The entire stack—front end, back end, and database—will sit with one developer, so deep, hands-on experience across each layer is essential.

Stack and tooling
The current plan leans on Node.js for server logic, Next.js for rendering and routing, and MongoDb for data persistence. Everything should be wired together with clean, testable JavaScript/TypeScript, Git-based workflows, and familiar DevOps practices (CI/CD, containerisation, cloud hosting of your choice).

Daily responsibilities
• Craft responsive, interactive UIs that feel native on web and mobile.
• Implement rock-solid user authentication and role-based access.
• Build REST/GraphQL endpoints and integrate them with the MongoDb data model.
• Optimise queries, indexes, and backups to keep data fast and safe.
• Ship iterative features in weekly sprints, write tests, review your own code, and document as you go.

Contract terms
• Duration: 24 months, 40 hrs/week (full-time).
• Commitment: individual contributor only—no agencies or team hand-offs.
• Experience: a minimum of three years in real-world MERN projects is non-negotiable; portfolio links or repos will be reviewed.

Acceptance criteria
1. All features listed above meet functional specs and pass unit/integration tests.
2. UI achieves >90 % Lighthouse performance and responsive design scores.
3. Code merges cleanly into main branch with CI checks green.

I will provide product requirements, UI wireframes, and access to existing assets; you provide the complete working codebase, tests, and deployment scripts. Continuous communication happens through Slack and weekly video stand-ups. If that sounds like the perfect long-term fit, prepare to dive straight into sprint one.

Skills: JavaScript, NoSQL Couch & Mongo, Node.js, AngularJS, MongoDB, Next.js, MERN, REST API

We need a Canadian-based company to perform a penetration test on a web application hosted in AWS. This is a small project for a short-term engagement, and we are not interested in individual freelancers. The work should include identifying vulnerabilities, testing security controls, and providing a clear report with findings and recommendations. Please apply only if your company is based in Canada and has experience with AWS environments.

About the role

Phenowise is a patient-centered health-data platform: patients and their caregivers record medical history, conditions, medications, symptoms, and daily trackers, with subscription billing and health-data provenance features. Because the product stores and shares Protected Health Information (PHI) across a multi-tenant, caregiver-delegated model, security is a first-class requirement.

We're engaging a penetration tester to perform an authorized, black/grey-box assessment of our web application, public APIs, and cloud environment, and to deliver actionable, risk-ranked remediation guidance. This is hands-on offensive testing against a modern serverless AWS stack, followed by a remediation retest.

What you'll be testing (technology context)
Frontend: React single-page app (multiple environments: production, staging, QA).
APIs: REST APIs on Amazon API Gateway backed by AWS Lambda (Node.js and Python), a mix of a legacy monolithic service and newer per-domain "router" microservices.
AuthN/AuthZ: Amazon Cognito (separate end-user and administrative/console user pools); authorization enforced in application code (not at the gateway).
Data: Aurora MySQL and PostgreSQL, DynamoDB, and a reference catalog DB; data reached via the RDS Data API and direct drivers.
Payments: Stripe subscription billing (checkout, portal, webhooks).
AI services: Python/LLM services (OpenAI/Bedrock-class models, vector search) that operate over patient-derived data.
Domain features: consent ledger, record lifecycle / caregiver transfer, and a health-data "minting"/provenance flow.

Key responsibilities
Plan and execute a full-scope penetration test against agreed targets, following a recognized methodology (OWASP WSTG / API Security Top 10 / PTES), within documented rules of engagement.
Test the web application for the OWASP Top 10 and beyond (injection, XSS, CSRF, SSRF, insecure deserialization, misconfig, sensitive-data exposure, CORS).
Perform deep API security testing, with priority on broken object/function-level authorization (BOLA/IDOR) across the multi-tenant patient/caregiver model — verifying that no user can read or mutate another patient's records via object identifiers.
Assess authentication & session security: Cognito token handling, JWT validation, token replay/expiry, cross–user-pool privilege escalation, password/2FA/reset flows, and account/caregiver delegation abuse.
Review cloud configuration & serverless posture: IAM least-privilege (over-permissioned execution roles), API Gateway config, S3 exposure, secrets handling in Lambda environments, and function-level injection/SSRF.
Test business logic: subscription/pricing manipulation and Stripe webhook integrity; consent bypass; record-lifecycle/caregiver-transfer abuse; provenance/mint signature verification and replay.
Assess AI/LLM surfaces for prompt injection, cross-tenant data leakage through model context, and unsafe tool/data access.
Evaluate PHI handling: data exposure in responses/logs/errors, excessive data return, and transport/storage protections relevant to HIPAA.
Produce a professional report and re-test confirmed fixes.

Required qualifications
4+ years of hands-on application and API penetration testing.
Demonstrated expertise in authorization testing / IDOR / multi-tenant isolation — this is the single most important skill for this engagement.
Strong AWS security knowledge: IAM, Cognito, Lambda, API Gateway, S3, RDS/DynamoDB; experience testing serverless architectures.
Proficiency with industry tooling (e.g., Burp Suite Pro, OWASP ZAP, Postman, nuclei, ScoutSuite/Prowler or equivalent) and comfort scripting custom checks (Python/JS).
Ability to read source code (Node.js and Python) to inform grey-box testing and validate findings.
Experience testing systems handling regulated/sensitive data and familiarity with HIPAA privacy/security expectations.
Clear written communication: risk-ranked findings (CVSS), reproducible steps, and practical remediation.

Preferred / bonus
Relevant certifications: OSCP, OSWE, GWAPT, eWPTXv2, CRTP/CARTP, AWS Security Specialty.
Healthcare security experience (HIPAA/HITRUST/SOC 2).
OAuth2/OIDC and Cognito-specific attack experience.
LLM/AI security (prompt injection, data-leakage) and/or Web3/smart-contract & signature testing.
Prior serverless/microservice assessment and secure code review.

Project Title

Fix Bugs, Add Validation and Improve Responsiveness in Existing MERN Stack Website

Project Description

I already have a MERN Stack portfolio website, and I am looking for an experienced developer to fix and improve the existing project.

The website is already developed, so I do not need a new website built from scratch. The main focus is on identifying and fixing existing bugs, implementing proper form validation, and improving responsiveness across all devices.

Required Tasks:

Identify and fix existing frontend and backend bugs
Add proper form validation and error messages
Fix Contact Form functionality
Ensure MongoDB data submission works correctly
Improve website responsiveness for mobile, tablet, and desktop
Fix UI issues such as alignment, spacing, overflow, and layout problems
Test the website across modern browsers
Fix any API integration issues
Ensure all existing features work properly after changes
Improve overall UI/UX without changing the core design

Important:
The source code is already available and will be provided to the selected freelancer. Please focus on debugging, validation, responsiveness, and improving the existing functionality rather than rebuilding the project.

Expected Outcome:
A bug-free, fully responsive, and properly validated MERN Stack portfolio website that works smoothly across desktop, tablet, and mobile devices.

Skills: JavaScript, Website Design, HTML, Node.js, Express JS, React.js, Web Development, CSS3, MongoDB, MERN

My WhatsApp Business account is already fully verified; the missing piece is a live Meta app that lets me run large-scale marketing broadcasts through the official Cloud API. I need you to step in, create the app in Meta’s developer portal, complete all required configurations (system user, phone number, webhooks, message templates), guide it through App Review, and hand it over ready for production traffic.

Once the app is live I want to be able to send segmented promos, coupons, and new-product announcements directly from my backend, so please wire up a lightweight example endpoint or script (Node.js or Python is fine) that shows how to trigger a broadcast to an uploaded contact list and how to pull delivery analytics.

To keep the hand-off smooth, make sure the final setup covers:
• Verified compliance with Meta’s marketing policy
• All necessary access tokens, webhook URLs, and template IDs documented
• A quick README walking me through rotating tokens and adding new templates

I’ll choose someone who can point to previous Meta/WhatsApp API launches rather than generic chatbot projects, so highlight that experience when you reply.

Skills: JavaScript, Python, Marketing, Google App Engine, Node.js, Digital Marketing, App Development, API Development

I want to bring to life a cloud-based platform that unifies three core functions a modern accommodation business needs: a real-time channel manager, a full property-management system, and an on-site POS, all knitted together through a third-party API.

Scope and objectives
The system must work smoothly for every accommodation style—hotels, vacation rentals, hostels and any hybrid in between—so configurability is crucial. Inventory, rates and reservations have to flow automatically between the PMS and the external API, keeping OTA listings perfectly in sync while preventing over-bookings. At property level, staff should be able to handle the entire guest journey from booking to check-out and settle ancillary charges at the POS without touching a second screen.

Key PMS modules I need built and ready for day-to-day use:
• Reservation management with multi-property support and availability grid
• Guest check-in / check-out workflows, including room moves and folio handling
• Housekeeping dashboard with room status updates and task assignment
• Customisable operational and financial reports (occupancy, revenue, POS sales, etc.)

POS requirements
The POS must post charges directly to a guest folio in real time, support multiple outlets (bar, restaurant, spa) and work on tablet or desktop browsers.

Integration & tech expectations
• Two-way sync through the chosen third-party API (JSON/REST) for rates, restrictions, availability and reservations
• Well-documented internal API so we can extend to mobile apps later
• Responsive, intuitive UI (React, Vue or similar) and a solid, scalable backend (Node, Laravel, Django—open to your recommendation)
• Git-based workflow, clear commit history and deploy scripts for staging and production environments

Acceptance criteria
1. Inventory and rate changes pushed from the PMS reflect on partnered OTAs asap and vice-versa.
2. A full guest booking cycle—including a restaurant charge posted via POS—must complete without manual data entry.
3. System generates accurate same-day revenue, occupancy and housekeeping reports.

If you have previously delivered hospitality-tech solutions or integrations of comparable complexity, let’s discuss your approach and timeline so we can map milestones and get started.

I’m building a fully-featured fintech website and need an experienced developer to take it from concept to production. The platform must let end-users create an account, sign in with a traditional email-and-password flow, and then manage their finances through an elegant, mobile-responsive interface.

Core modules will include user authentication, personalised dashboards, payment or transaction handling, rich data visualisations, and a lightweight admin panel. Strong application-level security (OWASP best practices, encrypted credentials, rate limiting) is mandatory, as is fast performance on both desktop and mobile.

My preferred stack is React or Next.js on the front end, backed by Node.js or Python services that talk to a PostgreSQL database and external payment/banking APIs. I intend to host on AWS or Vercel, so familiarity with CI/CD pipelines, infrastructure-as-code, and automated testing will be valuable.

Deliverables
• Production-ready source code with clean architecture and comments
• Deployed site (test and live environments) behind TLS and WAF
• Admin dashboard to manage users, transactions, and settings
• Documentation covering API endpoints, environment variables, and deployment steps
• Handover session to walk me through setup, security controls, and future scalability options

If you have a proven track record launching secure, responsive fintech or SaaS products with the technologies above, I’d love to hear how you would approach this build and a realistic timeline for each milestone.

Skills: JavaScript, Python, Web Security, NoSQL Couch & Mongo, Node.js, PostgreSQL, Next.js, CI/CD

We are building an AI-powered concierge that turns a WhatsApp request into a verified real-world outcome.

The customer-facing product lives entirely inside WhatsApp. Behind it is an agentic execution system that interprets intent, uses structured memory, connects to third-party booking/service APIs, handles failures autonomously, requires explicit confirmation before transactions, and verifies that the real-world action actually occurred.

We are looking for one highly capable senior full-stack/product engineer to work closely with our founder and a part-time CTO.

This is not a simple chatbot or prototype project. We want production-quality engineering from the beginning.

Initial scope includes: WhatsApp Business Platform integration; LLM tool/function calling; structured user memory; PostgreSQL/Redis; booking and service-provider API integrations; deterministic confirmation and execution workflows; retries, queues and idempotency; AI-assisted failure recovery; operator dashboard; payments; Arabic/English support and voice-note processing; AWS deployment, CI/CD, logging and observability.

Preferred stack: Python/FastAPI or TypeScript/NestJS for the backend, Next.js/React for the operator console, PostgreSQL, Redis and AWS. We will select one backend language before implementation and want to keep the architecture intentionally simple, avoiding unnecessary mixed-stack complexity.


We especially value engineers who have built AI agents, API-heavy SaaS products, booking/marketplace systems, automation platforms, voice agents or production LLM applications.

The successful candidate must be comfortable owning implementation end-to-end while working under architectural direction from our CTO.

Initial engagement: paid technical trial followed by an approximately 12-week MVP build, with strong potential for an ongoing role.

When applying, please show us one or two systems you personally built that are most comparable to this project. Explain what you personally implemented, the architecture used, and one difficult production failure you had to solve.

Please do not send a generic portfolio or agency introduction.
