Full-Stack Developer (AI Wrapper + Stripe) – 48hr MVP Build
Bilal is the reason people go to upwork--to find super high quality work at reasonable prices. Bilal delivered with speed and precision and was always available. I will absolutely be working with him on projects in the future. He's in a league of his own.

About Bilal

Job Success
Woodinville, United States - 12:22 pm local time
Most AI projects break in the same three places: RAG retrieval quality, cost per OpenAI request, and what happens when the LLM returns something wrong. Most full stack builds break somewhere different, usually in the data model nobody revisited after month one. I design for both, because an AI feature is only as reliable as the full stack application carrying it.
15 years of full stack development. 100% Job Success Score. Complete ownership from architecture through deployment.
AI ENGINEERING, AI AUTOMATION AND AI AGENTS
OpenAI and ChatGPT API integration, LangChain and LangGraph, RAG pipelines, retrieval augmented generation over private data, AI agents with tool calling, autonomous agent workflows, AI chatbot development, LLM application development, generative AI, prompt engineering, Pinecone vector search, embeddings, semantic search and AI workflow automation.
Every RAG build ships with an evaluation harness, so retrieval quality is measured rather than assumed.
💻 FULL STACK AND BACKEND DEVELOPMENT
Full stack development in Python and TypeScript. Backend with FastAPI, Django, Flask, Node.js and Express. REST API development, GraphQL, microservices architecture, authentication and authorization, role based access, row level security, background jobs, webhooks and third party API integration.
🎨 FRONTEND DEVELOPMENT
React and Next.js in TypeScript with Tailwind CSS. Server side rendering, static site generation, incremental static regeneration, state management with Redux and Zustand, dashboards, admin panels, and AI chat interfaces with streaming responses.
🗄️ DATABASES, CLOUD AND DEVOPS
Supabase, PostgreSQL, MongoDB, pgvector, schema design, Supabase Edge Functions and real time features. AWS, GCP, Docker, Vercel, Firebase and CI/CD pipelines for AI and full stack SaaS deployments.
WHAT CLIENTS HIRE ME TO BUILD
→ AI powered SaaS platforms and full stack SaaS MVPs taken from idea to live product
→ Full stack web applications with billing, roles, dashboards, admin and analytics built in
→ AI chatbots and LLM copilots embedded inside existing full stack applications
→ AI agents and AI automation systems with tool calling, retries and human approval steps
→ RAG pipelines and semantic search over private company data with citations and access control
→ OpenAI and ChatGPT integration into existing Python, Node.js and Next.js codebases
→ Full stack rescue work on stalled projects, including refactors and migrations
→ Stripe integration, payment integration, webhook automation and internal API integration
HOW I WORK
→ I tell you what I would build differently before you hire me, not after
→ Architecture and tradeoffs written down before the first line of code
→ Weekly working demos instead of month long silences
→ LLM latency and cost per request treated as requirements, not afterthoughts
→ Clean, documented, scalable Python and TypeScript you can hand to another engineer
If you need an AI engineer or a full stack developer for RAG, LangChain, OpenAI integration, AI agents, AI automation, or a complete full stack SaaS build in Python, React and Next.js, send me a short note on what you are building. I will reply with how I would architect it and the one part I would push back on.
