Best PHP engineer jobs in the U.S.

I need a developer to build a responsive, mobile-friendly website for a calendar app relaunch. The site should include a homepage, about page, features page, pricing page, and contact page, with a clean, modern design. You will also set up a contact form and ensure the site is easy to navigate. The project should be completed in under 15 days, with clear communication and timely updates throughout the development process.

The current website is sparkcal.com

Nothing on the current site will be used other than the text/content. Logos, screenshots and colors for the relaunch are completely different than what is there now. Do not send me mockups using the old website design and logos. I have attached the branding pdf for the redesign to give you an idea of how different it will be.

I have logo files in several different colors and orientations. Screenshots of the new app will be provided as the design progresses.

Proposals with figma mockups will go to the front of the line.

Need a PHP developer to work with existing code and improve current data collection tools. The project includes modifying current functionality, expanding capabilities, and helping implement new features that support ongoing data collection needs. You should be comfortable reviewing existing systems, making targeted updates, and collaborating on improvements that align with the project goals. Experience working with similar tools and delivering reliable, maintainable code is important.

We’re a law firm, and we’re taking our Legal Operations AI MVP into production. It replaces a fair amount of our legacy legal system. We’d like a senior AI product engineer on call around the clock for the first week, so that when something breaks (and something always does), someone who understands both the AI and the full stack can jump in quickly.

What we built

It isn’t a ChatGPT wrapper. It’s an internal AI operations platform that works with our documents, emails and existing systems to cut down on repetitive admin work.

Day to day, the team uses it for:

Client and matter intake
Document and email summarisation
Pulling out dates, parties, obligations and action items
Building matter timelines
Searching our internal knowledge base
Drafting first-pass emails and notes
Routing tasks to the right people

Every answer is grounded in RAG over our own documents (embeddings, vector search and semantic search) and comes with source citations, so people can see where it came from. Retrieval respects matter-level permissions.

Under the hood:

AI layer: model-agnostic. Different tasks go to different models, including OpenAI GPT models, Anthropic Claude, Gemini, Grok, Groq and Llama, partly through OpenRouter and the Vercel AI SDK, with fallback when a provider goes down.
Agents: AI agents use tool calling and MCP to take actions. Structured JSON outputs get validated before anything happens.
Business rules: deterministic rules sit apart from the AI. Anything sensitive or uncertain waits for human review.
Stack: Next.js, React, TypeScript, Node.js, PostgreSQL and AWS, with private S3 storage, background jobs, queues and webhooks. A few older PHP/WordPress pieces are still connected, along with integrations into email, our matter-management software, billing and Stripe.

What we need from you

For seven days from go-live, be reachable at any hour. In practice that means:

Monitoring: keep an eye on errors and logs, LLM usage and costs, and any AI actions that failed or came back uncertain.
Fixing: when something goes wrong, work out why and fix it. That might be:
a model API outage or rate limit
a document that won’t ingest or OCR properly
retrieval pulling the wrong sources
an agent workflow getting stuck
a webhook or queue backing up
someone who can’t access a matter they should be able to (or can access one they shouldn’t)
Escalating: some things we need to hear about straight away:
possible data leakage
prompt injection, including instructions hidden inside documents
hallucinations or answers stated more confidently than the sources support
confidential data heading to an AI provider it shouldn’t
Legal work has very little tolerance for confidently wrong output. The system is meant to say “I don’t know” rather than guess, and we want to confirm it actually does.
Incident log: keep a short note of each incident: what happened, why, and what you did.
End-of-week summary: what held up, what didn’t, and what you’d prioritise next.

Response times

Critical (system down, or anything touching security or confidentiality): acknowledge within 30 minutes, day or night.
Everything else: within 4 hours.

Terms

$10/hr, billed only for time you actually spend on alerts, investigating and fixing.
One week from go-live, with the date agreed together.
Our usual rules still apply:
no confidential data to unapproved AI providers
least-privilege access
audit logging
human sign-off on sensitive actions
If it goes well, we’d like to keep working together on the next phases.

Who this suits

Ideally you’ve built and run production AI or SaaS products yourself, not just prototypes. Technical founders, founding engineers, forward deployed engineers and full-stack AI engineers would all fit well.

A few things are a bonus but not required:

Trust & safety, abuse detection or prompt injection testing
Voice, transcription or other multimodal AI work (ElevenLabs, Runway and so on)
Experimenting with local models, fine-tuning or Unsloth

# WordPress Developer Needed – Build IT Health Check Questionnaire, Scoring System & PDF Reports

**Budget: £400 Fixed Price**

**Project Type:** WordPress Development / CMS Development

**Website:** https://gentrixit.co.uk

## Project Overview

We are Gentrix IT, a UK-based managed IT services provider.

We are looking for an experienced WordPress developer to design, build and launch a professional, interactive **IT Health Check** on our existing WordPress website.

The purpose of the Health Check is to allow businesses to complete a free 12-question IT assessment, receive a personalised IT Health Score and downloadable PDF report, and understand where their business could improve its IT systems and cybersecurity.

The assessment will also help us generate enquiries from businesses interested in our managed IT services.

**This is a non-AI project.** All scoring, risk classifications and recommendations will be generated using predefined rules.

We have already prepared a detailed project specification, including the questions, answer options, scoring methodology, recommendation requirements and preferred PDF design.

## Project Requirements

**1. WordPress Landing Page**

Design, build and publish a professional IT Health Check webpage on our existing WordPress website.

The page must include:

- A modern design matching our existing Gentrix IT branding.
- An engaging introduction explaining why IT health matters to businesses.
- A clear call-to-action button to start the assessment.
- A fully responsive design for desktop, tablet and mobile.
- Integration of the questionnaire directly

I’m looking for an experienced web developer to help assess the feasibility of creating a UK-based adult lifestyle membership website exclusively for people aged 50 and over.

I already have a working HTML design prototype showing the general appearance and layout I would like.

The eventual website would include:

- Member registration and profiles for individuals and couples
- Private messaging between members
- Photo uploads and privacy controls
- Location and postcode-based member searching
- Online status indicators
- Administrator tools for profile verification and moderation
- Mobile-friendly design
- Appropriate security, UK data protection and online safety measures, including age assurance

**IMPORTANT: This initial job is NOT to build the complete website.**

I am looking for a small, fixed-price technical feasibility assessment with the following deliverables:

1. Recommend suitable, actively maintained dating or community software that could be adapted for this project, rather than developing everything from scratch.
2. Explain the software’s licensing costs, ongoing costs, limitations and suitability for an adult-oriented membership website.
3. Provide a small demonstration or walkthrough showing how the proposed software works and how my existing HTML design might be incorporated.
4. Identify significant technical, privacy, security and UK regulatory considerations that would need specialist review before launch.
5. Provide a separate, itemised quotation and estimated timescale for developing the full website.

My initial budget is approximately $300 USD for this assessment only. I understand that full development would be a separate project with a substantially larger budget.

I am not a technical expert, so I would appreciate clear explanations in plain English.

Please include examples of relevant membership, dating or community websites you have worked on, and confirm that you are comfortable working on a lawful adults-only lifestyle website.

I am exploring options and am not yet committing to full development.

I need help creating a website for my business. The project involves building a functional online presence that is clean, user-friendly, and easy to navigate. I am looking for someone who can handle the development process from start to finish and deliver a reliable website that meets my needs. Please share relevant examples of similar work and your approach to building and launching a website.

I need help building a custom element in GoHighLevel that I have already created in WordPress. The goal is to recreate the same functionality and user experience in GoHighLevel so it works smoothly within the platform. I’m looking for someone who can translate the existing WordPress setup into a custom GoHighLevel element and ensure it performs reliably. Please share relevant experience with custom element development and similar platform integrations.

🎯 Tracking Engineer — GTM, sGTM/Stape, GA4, Google Ads Conversion Tracking (Google Ads Agency)

We're BERK Labs, a Google Ads agency, and we're hiring a second tracking engineer to work alongside our lead engineer. You'll build and fix conversion tracking for our clients across Google Ads, Microsoft Ads and Meta — steady, ongoing work that grows as fast as you prove yourself. We handle all client communication; you focus on the build.

💡 Who we hire: we care about engineering depth and how quickly you learn our procedures, not your Upwork history. Our lead engineer joined with a thin Upwork profile and a deep technical one. Newer profiles are welcome.

🛠️ What you'll actually do:
✅ Client-side and server-side Google Tag Manager — nearly every client runs a Stape-hosted sGTM container
✅ Google Ads conversion tracking done right: enhanced conversions, gclid/gbraid/wbraid handling, Consent Mode v2
✅ Offline conversions from CRMs back into the ad platforms — especially HighLevel (several clients run on it), plus HubSpot, Salesforce and Pipedrive
✅ Call tracking with CallRail and Google forwarding numbers, and getting calls into Google Ads as conversions
✅ GA4 events, dataLayer specs and enhanced e-commerce on Shopify, WooCommerce, WordPress, Webflow and Squarespace
✅ Meta Pixel + Conversions API; Microsoft Ads UET
✅ Monthly tracking audits — checking each client's live site against its Data Plan and fixing what drifted (clients change their sites without telling anyone)
✅ Rare, minor site code changes — never anything that touches design

🚫 What you won't do:
❌ Manage ad campaigns
❌ Build websites or landing pages
❌ Deal with clients directly

📋 What we're looking for (we'll ask for proof):
🔹 GTM + GA4 + dataLayer implementation without a developer on the client side — you'll usually be the only technical person on the project
🔹 Server-side GTM on Stape (or Cloud Run / self-hosted)
🔹 At least one end-to-end offline conversion pipeline from a CRM back into an ad platform
🔹 A real programming background — JavaScript at minimum; Python, PHP or Go a plus. You read and write code, not just click through interfaces
🔹 Strong written English — we work async in Slack and Monday, so clear writing matters more than accent

🌟 Bonus points:
✨ HighLevel / GoHighLevel attribution — UTM templates, source rules, number pools, "Add to Google Ads"
✨ Spam prevention — bot filtering in GTM, reCAPTCHA / Cloudflare Turnstile / honeypots, keeping junk form fills out of conversion data
✨ Web security — CSP for sGTM, consent management (GDPR/CCPA), cookie governance, securing API keys in tag templates
✨ Fluent use of AI coding tools (Claude, Cursor, Copilot) to ship faster and document as you go — we coach on this

👤 Who you are:
⚡ Responsive — you reply within your working day and turn most tasks around in 3–4 business days
💬 Proactive — you flag scope creep before it becomes a problem
🧹 You document your work so another engineer can read it a year from now
📈 You get better every month — we invest in coaching, and we hire people who use it

🤝 How we work:
📌 Monday.com for tasks, Slack for comms, Upwork time tracker required — no exceptions, and no work or payment outside Upwork
📌 Clear priorities, deadlines and dependencies — you'll never be guessing
📌 Work when you want — we never require weekends or holidays, but if you prefer them, that's fine with us
🎁 Hours ramp quickly for people who deliver; performance bonuses for strong communicators
🚷 Individuals only — no agencies or staffing firms, please

🪜 Hiring process:
1️⃣ Written screening (your proposal and the questions below)
2️⃣ A small paid trial task
3️⃣ Technical interview with our lead tracking engineer
4️⃣ Ongoing hourly contract

📝 To apply, include all three:
1️⃣ The word "kumquat" somewhere in your cover letter so we know you read this
2️⃣ 2–3 work samples covering this stack, with rough hours per project
3️⃣ Your answer to this scenario, taken from our real client work: A medical aesthetics clinic runs Google Ads and uses HighLevel as its CRM. Leads arrive two ways — a form on the landing page and phone calls to a CallRail tracking number. The clinic wants Google Ads to optimize toward "consultation booked" (a pipeline stage in HighLevel), not toward form fills or calls. Walk us through how you'd architect it end-to-end: click-ID capture, how the ID survives inside the CRM, how the booked-consultation event gets back into Google Ads — and what's different, or impossible, for the phone-call leads.

Looking forward to your application! 👋

We have a near-complete WordPress website for a Singapore property agent (new condo launches). The core build is done by our existing developer: custom block theme, custom post types for projects, districts, MRT stations, schools and articles, plus a project data import. What remains is visual polish to match our Figma design exactly, followed by ongoing maintenance. We want to go live as soon as possible.

Working with our existing developer: You will work alongside our existing developer, who continues to own the custom code (project data import and sync, search and filters, Google Maps integration). You will own the visual layer and content. We will set up a 30-minute handover call where he walks you through the custom blocks and how project data works, and we will keep a shared change log so your work and his never overlap or overwrite each other.

Part A: One-time visual fixes (fixed price)
- Compare each page on our staging site against the Figma design and fix all visual differences: spacing and padding between sections, text alignment, font sizes and weights, image cropping and ratios, overlapping text, and missing icons.
- About 14 page templates: Home, Project page, New Launch hub, District hub and profile, MRT line and station pages, Primary School hub and profile, TOP Year page, Tenure hub plus 3 tenure pages, Insights (blog) listing and article pages, Resale page, Showflat page.
- Fix broken internal links and buttons (e.g. links still pointing to old /wordpress/ paths, "Browse all" and "Explore all" buttons not linking to the right pages).
- Check and fix every page on mobile and tablet.
- Use the existing custom blocks and theme styles wherever possible so the site stays editable from the WordPress admin. No new page builders or heavy plugins without asking first.
- We will give you a numbered list of known issues, but we expect you to find and fix any other differences from the Figma too.

Part B: Ongoing maintenance (adhoc or ongoing to be discussed, estd 2-6hrs/month)
- Edit text, images, FAQs and page sections.
- Add or update project listings: rename projects when they get an official name, upload new project images and details, and update project content from an Excel sheet we provide.
- Publish new blog articles we write (formatting, images, categories, internal links).
- Monthly WordPress core, theme and plugin updates, with a backup before every update, coordinated with our existing developer so updates do not break his custom code.
- periodic data upload/refresh
- fix any aesthetic-related issue when raised

Not in scope: changes to the project data import and sync code, search and filter logic, or the Google Maps integration. These stay with our existing developer. If you spot a bug in these areas, log it in the shared change log and flag it to us rather than changing the code yourself.

How we work:
- All changes are made on the staging site first, never directly on the live site.
- Take a full backup before starting and before any major change.
- Log every change you make (date, page, what changed) in our shared change log.

Must have:
- Solid WordPress experience, including block themes (Gutenberg / Full Site Editing) and editing theme CSS and basic PHP templates.
- Able to follow a Figma design accurately, down to spacing and typography.
- Comfortable working in a codebase someone else built, and communicating clearly with another developer.
- Good written English and responsive within 24 hours on weekdays.

Nice to have: Experience with custom post types and ACF, real estate or listing websites.

1. HTML to WordPress Conversion

Convert the supplied HTML/CSS/JavaScript website into WordPress using Elementor.

Maintain the visual design, typography, spacing, layout, animations, and interactive elements.

Ensure the website works beautifully across desktop, tablet, and mobile.

Preserve the intended user experience and functionality.

2. Modular and Reusable Architecture

This is one of our most important requirements.

We want a website built with reusable Elementor components so our internal team can easily create new pages without requiring custom development.

This includes:

Reusable sections and blocks for landing pages.

Global design settings for typography, colors, buttons, and other shared elements.

Reusable headers, footers, CTAs, forms, and content sections.

Page templates for commonly used layouts.

A structured component library within Elementor.

Consistent styling and design standards across pages.

For example, we should be able to create a new landing page by combining existing hero sections, content blocks, testimonials, CTAs, and forms without rebuilding them from scratch.

3. Performance and Technical Quality

Optimize the site for loading speed and mobile performance.

Use clean, maintainable code and avoid unnecessary plugins.

Ensure proper responsive behavior across common devices and browsers.

Implement basic technical SEO best practices.

Maintain accessibility best practices.

Ensure animations and interactive components perform smoothly.

4. CMS and Content Management

Make website text, images, buttons, and standard page sections editable through Elementor.

Set up appropriate templates and content structures.

Ensure our team can add, remove, duplicate, and rearrange sections easily.

Minimize reliance on custom code for everyday content changes.

5. Testing and Handoff

Build and test the site in a staging environment.

Perform desktop, tablet, and mobile QA.

Resolve bugs and visual inconsistencies before launch.

Provide a short walkthrough or recorded tutorial showing how to use the reusable components and build new landing pages.

Deliver the completed WordPress website, templates, and any custom code with full administrative access.

Ideal Candidate

We're looking for someone who:

Has extensive experience with WordPress and Elementor / Elementor Pro.

Has successfully converted custom HTML websites into Elementor.

Understands modular web development and reusable component systems.

Access to our WordPress hosting or staging environment.

Feedback and guidance during development.

Deliverables

Fully functional WordPress website built with Elementor.

Accurate reproduction of the provided website design.

Reusable Elementor section and page templates.

Global design settings and reusable components.

Fully responsive layouts.

Optimized website performance.

Completed QA and bug fixes.

Documentation or video walkthrough for our team.

How to Apply

Please include:

Examples of at least two custom Elementor websites you've developed. We'd especially like to see examples where you converted an existing design or HTML website into WordPress.

A brief explanation of how you would approach building reusable sections and templates.

Your experience working with custom HTML, CSS, JavaScript, and animations in Elementor.

Your estimated timeline and fixed-price quote.

Whether you'll be completing the development yourself or working with a team.

Hello there,

My website is slow in China, Can you help to check, and solve.

Thank you!


Jackie

We run a tour company website. It is slow on mobile and fails Google's Core Web Vitals. Many of our visitors are overseas (Hong Kong, Malaysia), and the site is hosted in Tokyo.

Current PageSpeed Insights results (homepage):
- Real-user data (mobile): LCP 4.6s, TTFB 2.1s, FCP 3.7s (Core Web Vitals: Failed)
- Lab test (mobile): Performance 55, LCP 18.3s, FCP 6.9s
- Lab test (desktop): Performance 35, LCP 7.7s, Total Blocking Time 910ms

Our own investigation suggests the main causes are:
- A large hero image (likely the LCP element)
- Slow server response for overseas visitors (no CDN)
- Heavy JavaScript (page builder / slider / third-party scripts)

Before starting, please send:
1. Your diagnosis of the top 3 causes, based on PageSpeed Insights
2. Your planned fixes
3. Any costs outside this job (e.g. hosting upgrade, paid CDN or plugin). Do not purchase anything without our approval.

Acceptance criteria (job is complete when all are met):
- Mobile PageSpeed LCP under 3s on the homepage and 2 tour pages we nominate
- Mobile Performance score 80+ on those pages
- No visual or functional breakage: menus, sliders, enquiry/contact forms, and all language versions (English and Traditional Chinese) must work
- Improvements must be genuine for real users. No techniques that only target Lighthouse (e.g. hiding content from test bots).
- A written list of every change made (plugins added/removed, settings, image changes, CDN setup), so our in-house developer can maintain it

Requirements:
- Full backup or staging copy before making changes
- Proven experience with Core Web Vitals / page speed on [WordPress]. Please share 1–2 before/after PageSpeed examples.
- Work alongside our in-house developer, who will review the changes

I own a legitimate handyman business website hosted on HostGator and am seeking an experienced WordPress specialist for authorized security remediation and website maintenance.

The website has experienced recurring security issues. Previous cleanup attempts temporarily resolved the problems, but suspicious PHP files and unauthorized blog posts have subsequently been detected.
Scope of Work:

Inspect WordPress files, plugins, themes, and database for unauthorized modifications.

Identify the likely source of recurring security issues.

Remove unauthorized code, suspicious content, and unwanted WordPress posts while preserving legitimate business content.

Review administrator accounts, file permissions, and relevant security configurations.

Apply appropriate WordPress security updates and hardening.

Restore normal website functionality.

Provide a brief report explaining the findings, corrective actions, and recommendations to prevent recurrence.

The WordPress administration dashboard is currently inaccessible. The specialist must be comfortable performing the initial investigation and recovery through HostGator cPanel, File Manager, phpMyAdmin, and secure server access.

The goal is to restore WordPress access, investigate the recurring security issues, remove unauthorized content and malicious code, and secure the website against further compromise.

All work is authorized by the website owner and is strictly limited to defensive maintenance and recovery.
Preferred Experience: WordPress security remediation, PHP, malware cleanup, database inspection, and HostGator/cPanel hosting.

Please describe your experience resolving recurring WordPress security incidents and how you would approach this project.

Hello!

I'd like to invite you to take a look at the job I've posted. Please submit a proposal if you're available and interested.

https://repair.mbgapplianceservices.com/

i'm looking to redesign this website..? make it SEO and AI optimized..

I’m looking for a developer to create an automated bot that can monitor a website and purchase specific items automatically when they become available. The bot should be reliable, efficient, and able to handle the purchase process quickly once the desired items are in stock.

I'm looking to purchase items from a single website. I also have access to a dedicated server and/or virtual machine if needed.

We are looking for a senior AI automation engineer or a small, experienced team to build an integrated e-commerce operating system.

This is a hands-on implementation project—not a strategy presentation, chatbot or collection of disconnected automation demos.

We want to start as soon as possible. Propose your fastest realistic delivery schedule, with fixed prices, clear milestones and measurable acceptance criteria.

THE GOAL

Build a system that continuously:

Researches products → prepares stores and offers → creates marketing assets → runs approved advertising → publishes organic content → handles community interactions → measures results → improves the next round of decisions.

One human approves key decisions through WhatsApp. Routine actions execute automatically within approved rules, permissions and spending limits.

The system must record what it recommended, why, what was approved, what it executed and what happened afterward.

We have a detailed specification of approximately 50 pages to share before the final scope and price are locked.

PHASE 1: 14 FUNCTIONAL ROLES

1. Product Scanner
Collect signals from approved sources such as Winning Hunter, accessible Meta advertising signals, TikTok Shop, search trends and reviews. Produce scored opportunities with sources, timestamps and clearly stated uncertainty. Do not invent unavailable competitor metrics.

2. Deep Researcher
Investigate shortlisted products in parallel: customer problems, reviews, demand, competition, suppliers, delivery assumptions and potential margins. Present the top three opportunities for human approval.

3. Store and Offer Builder
Use our approved Shopify template to prepare product pages, offers, bundles, FAQs, emails and product images. Work within authorised stores. Identify any store-provisioning or account-setup steps that require manual action.

4. Store QA
Check mobile layout, agreed performance targets, variants, pricing, inventory, checkout per target market, pixels/CAPI and unsupported claims. Create a short approval card before publication. Block launch when required checks fail.

5. Media Buyer
Execute configurable Meta advertising rules: testing, scaling, cost caps, broad targeting, existing post IDs, winner selection, kill thresholds and budget adjustments. Include minimum-data requirements and cooldowns. Rules must be in configuration, not buried in code.

6. Creative Writer
Generate scripts, hooks, headlines, ad copy and static-ad concepts based on product facts, approved positioning and previous results.

7. Creative Producer
Generate or render approved images, AI-UGC and voice assets through selected providers. Handle formats, versions, approvals and uploads. No fabricated customer testimonials or unsupported product claims.

8. Marketing Auditor
Independently check proposed and executed marketing actions against permissions, spending ceilings and policy rules. Detect unexpected changes, pause unsafe activity and reverse supported changes where appropriate.

9. Performance Analyst
Collect and reconcile hourly advertising, store and profit data. Report spend, orders, revenue, acquisition costs and margin using agreed definitions. Distinguish platform-attributed conversions from observed store orders.

10. Organic Publisher
Repurpose approved winning creatives, schedule content and track links and attributable orders per post. The target architecture should support 10–20 authorised accounts per agreed platform. State exactly how many accounts and which platforms your Phase 1 quote includes.

11. Community and Inbox
Process accessible comments and DMs across the agreed channels into six buckets: product questions, purchase intent, order/delivery questions, complaints/returns/refunds, positive or neutral engagement, and spam/abuse.

Answer appropriate messages from an approved fact sheet. Escalate complaints, sensitive account issues and uncertain cases. Do not blindly reply to everything or invent answers.

12. Cash and Learning
Refresh spending allowances hourly using available balances, reserves, committed costs and runway assumptions. Enforce shared allowances before spending increases.

Run a nightly review that updates product and creative rankings and proposes rule changes. The system may not independently rewrite its safety limits or expand its spending authority.

13. Orchestrator
Manage schedules, queues, dependencies, product/country state, retries and recovery. Send WhatsApp approval cards, concise digests and urgent alerts. Approvals must identify the exact action, target account, amount and expiry.

14. Reserve Auditor
Provide an independent second check for higher-risk actions across departments. This role cannot approve its own proposed actions or override the human’s limits.

ARCHITECTURE AND SCALE

These are 14 functional responsibilities, not a requirement for 14 separate applications or model calls.

Use the simplest maintainable architecture that delivers the agreed behaviour. Deterministic code should handle calculations, permissions and enforcement; AI should handle tasks that actually benefit from it.

Independent tasks must run in parallel per product and country. Dependent actions must still wait for the required data, QA and approvals.

Phase 1 must prove the full workflow on a controlled initial product/market setup and demonstrate isolated parallel execution across 10 product/market jobs. We are not asking to launch 10 paid campaigns simply to test concurrency.

Phase 2 will expand capacity or split responsibilities only where operational results show a bottleneck. Do not move the core Phase 1 roles into Phase 2 without explicitly agreeing this.

PREFERRED STACK AND INTEGRATIONS

Python/FastMCP, Postgres, Redis and Docker.

Shopify Admin GraphQL, Meta Marketing API, TrueProfit, relevant payment/balance sources, Klaviyo, TikTok, Google Drive, AI-UGC/voice APIs and WhatsApp Business API.

Alternatives are welcome where they reduce cost or complexity without weakening reliability, ownership or functionality.

Before implementation, identify the supported integration route, required permissions, approval dependencies and costs for every provider. No silent substitutions, undisclosed manual steps or promises based on API access that has not been checked.

Validate TikTok publishing feasibility specifically. Propose an approved provider or a clearly identified human step where required. Do not build around bypassing platform restrictions.

SAFETY AND DATA REQUIREMENTS

All money-changing actions must pass central permission and budget checks. Parallel workers must not each spend the same remaining allowance.

Use versioned rules, authenticated approvals, duplicate-action protection, bounded retries, rate-limit handling, monitoring and a global kill switch. Reject expired or replayed approvals.

Missing or stale financial data must block spending increases. Document platform reporting delays and any limits on how quickly external campaigns can actually be stopped.

Payment/balance integrations are read-only unless a specific write action is separately authorised. Autonomous bank transfers, supplier payments and refunds are outside the default scope.

Do not persist raw customer names, addresses, emails, phone numbers or message bodies in the agent database or logs. Keep customer records in their source platforms. Document and obtain approval for any necessary identifiers or temporary processing, and redact customer details before model calls.

Treat scraped pages, reviews and incoming messages as untrusted content, not instructions that can override system permissions.

PROPOSED MILESTONES

M1 — Paid pilot and integration validation
One Shopify store and one Meta account running collect → recommend → approve → execute. Demonstrate one agreed low-risk action, rejection handling, audit logging and duplicate-action protection.

The reference pilot budget is $800, with a target of one week after the required access is available. Confirm feasibility or explain the specific adjustment you propose. This is not the total project budget.

M2 — Research, store and offer workflow
Demonstrate sourced product scoring, parallel research, shortlist approval, a generated product page, QA checks and controlled publication.

M3 — Creative and paid marketing workflow
Demonstrate creative generation and upload, configured advertising rules, hourly analysis, independent auditing and budget enforcement.

M4 — Organic and community workflow
Demonstrate publishing through the agreed supported channels, tracked links, the six inbox categories, fact-based responses and human escalation.

M5 — Integrated operation and learning
Connect all 14 roles, demonstrate parallel product/market execution, hourly cash controls, nightly learning, WhatsApp approvals and recovery from integration failures.

M6 — Acceptance, deployment and handover
Complete the agreed monitored test period, resolve acceptance-blocking defects and deliver the deployment, source code, configuration, tests, documentation and operating instructions.

You may propose a better milestone structure, but every Phase 1 requirement must map to a named deliverable. Clearly distinguish developer-controlled delivery dates from external approval dependencies.

WHAT COUNTS AS DONE

Each milestone needs a written test plan agreed before work starts.

The final acceptance tests must demonstrate:

- A complete approved product-to-marketing-to-results workflow using real integrations in our environment.
- No execution of rejected, expired or unauthorised actions.
- No duplicate external action when a webhook, job or approval is replayed.
- Correct isolation and shared-budget enforcement across concurrent jobs.
- Blocking and alerting when required financial data is stale or unavailable.
- Working pause controls, retry handling and documented recovery behaviour.
- Hourly reporting, nightly review and traceable decision/action logs.
- A handover that allows another competent developer to deploy and operate the system.

Required functionality cannot be accepted on mock data alone. Test fixtures are appropriate for failure scenarios, but must be labelled.

Commercial results such as winning products or a particular ROAS are not software acceptance criteria. Correct implementation of the agreed workflow and rules is.

FIXED PRICE, PAYMENT AND SUPPORT

Fixed-price milestones only. Quote the complete Phase 1 cost, not just the pilot.

Each milestone will be funded through Upwork before work starts. Payment approval will follow successful completion of its written acceptance tests, subject to Upwork’s review and dispute procedures.

Incomplete work or reproducible defects against the agreed scope will be returned for correction. Fixing those defects is included in the milestone price. New features and scope changes require written approval and a separate quote before work begins.

Include a 30-day post-handover warranty for reproducible in-scope defects. Quote ongoing maintenance and third-party API changes separately.

Disclose infrastructure, model usage, rendering, messaging, subscriptions and other recurring charges separately from development fees. Include operating-cost estimates for the initial setup and the proposed expanded capacity.

Development must take place in our repository, with deployment under our control. Deliver custom source code, configuration, tests and documentation, and disclose third-party components and licences. Ownership of paid custom deliverables must be included.

TIMELINE AND WORKING STYLE

Start as soon as possible and propose the fastest schedule you can genuinely deliver.

Provide a specific start date, delivery date for every milestone and final completion date. “ASAP” by itself is not a timetable.

Work in small, testable releases: build → test safely → demonstrate → release → improve from real results.

Keep updates brief and useful: completed work, evidence, blockers and the next delivery date. Raise blockers immediately rather than waiting until a deadline is missed.

We value engineering judgement. Challenge unnecessary complexity and suggest cheaper or simpler approaches where they achieve the same outcome.

YOUR PROPOSAL MUST INCLUDE

1. Relevant production examples and your personal contribution.
2. Your proposed architecture and the main integration risks.
3. Fixed total price and fixed price per milestone.
4. Start date, milestone dates, final delivery date and committed team capacity.
5. Acceptance tests, required access, external dependencies and explicit exclusions.
6. Recurring operating costs, included support and anything you would simplify.

Please review the full specification before confirming your final fixed-price commitment. No unpaid custom implementation is requested; the pilot is a paid milestone.

All pre-contract discussions and all project payments will remain on Upwork. WhatsApp is part of the system we are building, not a request to move the hiring process off-platform.
