Generative AI Developer.
RAG Systems & AI Agents
That Actually Ship.
Most AI projects die in the same spot: they work in a notebook and fail in real use. I fix that part. I build RAG systems, AI agents, and custom GPT integrations that go live in your real workflow, not stuck in a demo. 9 years in software, the last stretch spent only on Generative AI apps that ship. Milestone billing. Full code ownership.
Generative AI Developer.
9 Years Making AI Work In Production.
I am a Generative AI developer with 9 years in software. The last stretch has been spent almost entirely on Generative AI applications that ship: RAG systems, AI agents, custom GPTs, and OpenAI and Claude integrations built for businesses across the US, UK, Europe, and Australia.
Most AI projects die in the same spot: they work in a notebook and then fall apart in real use. The difference here is the 9 years of engineering behind the AI work. I do not stop at a clever prompt or a demo; I build retrieval pipelines, agent logic, and integrations that go live in your real workflow, return the same answer twice instead of random output, and keep working once real users and real data hit them.
Every engagement runs on fixed-price milestone billing and full source-code ownership. You know exactly what you are getting, what it costs, and when it ships.
Generative AI, End To End.
From Prototype To Production.
I build the Generative AI systems businesses actually need in production: RAG over your own data, agents that complete real tasks, custom GPTs, and the engineering that keeps them reliable once live users hit them.
RAG System Development
Retrieval-augmented generation over your own documents, knowledge base, and data. The model answers from your sources with citations, not hallucinations. Chunking, embeddings, vector search, and reranking tuned for accurate, grounded responses.
AI Agents & Agentic Workflows
Agents that complete real multi-step tasks instead of just chatting: calling tools and APIs, querying databases, making decisions, and handing off cleanly. Built with guardrails and fallbacks so they finish the job without going off the rails.
Custom GPT & LLM Integration
Custom GPTs and OpenAI / Claude integrations wired into your real workflow, your CRM, your docs, your support inbox, your app. Not a standalone toy, but an assistant connected to the tools your team already uses every day.
Prompt Engineering & Production Backend
The part that makes AI ship: prompt workflows that give the same answer twice, not random output, plus the backend, deployment, monitoring, and error handling that keep an AI feature alive under real traffic. 9 years of software engineering behind every build.
Generative AI Services That Make It To Production
RAG systems, AI agents, custom GPTs, and the engineering that keeps them reliable. Every engagement is fixed-price, milestone-billed, and scoped in writing before work begins.
RAG System Development
Retrieval-augmented generation over your own documents and data. The model answers from your sources with citations instead of hallucinating. Chunking, embeddings, vector search, and reranking tuned for grounded, accurate answers.
AI Agents & Agentic Workflows
Agents that complete real multi-step tasks, calling tools and APIs, querying data, making decisions, with guardrails and fallbacks so they finish the job. Built to go live, not stay stuck in a demo.
Custom GPT Development
Custom GPTs and assistants wired into your real workflow: your docs, CRM, support inbox, or app. Trained on your knowledge and connected to the tools your team already uses, not a standalone toy.
OpenAI & LLM API Integration
OpenAI, Claude, and other LLM providers integrated cleanly into your existing stack, chatbots, document processing, data extraction, and AI features built for a measurable outcome rather than a proof of concept.
Prompt Engineering & AI Reliability
Prompt workflows that give the same answer twice, not random output. Structured outputs, evals, guardrails, and testing so your AI behaves predictably under real users and real data.
AI App Backend & Deployment
The engineering that makes AI ship: backend, APIs, databases, deployment, monitoring, and error handling around your AI feature. 9 years of software experience so it survives contact with production.
Built to stay live, not just to demoLive Projects. Real Results.
Production systems shipped end to end across SaaS, eCommerce, fundraising, and fleet management. This is the engineering track record behind the AI work, the reason RAG systems, agents, and GPT builds I deliver actually survive real users and real data. Each delivered on scope with full documentation and code ownership.
Broken Payments. Missing Developer.

Client: Randy J. Verified Upwork Client
Previous developer vanished with 60% of the build done. Checkout was broken, payments were failing silently, Stripe webhooks were misconfigured, and there was zero documentation. Real orders were being lost every day the store stayed down.
Written code audit first, no code touched. I identified the Stripe webhook misconfiguration, the SQL injection vulnerabilities, and the broken order management panel within 48 hours. A fixed-price milestone plan was delivered before a single change was made. Randy had full staging access at every step.
- Stripe webhook endpoints rebuilt and verified, silent payment failures eliminated completely
- Payment flow tested end-to-end across all checkout paths before going live
- SQL injection and CSRF vulnerabilities patched across the entire codebase
- Admin reporting panel rebuilt with real-time order tracking and payment status
- Full codebase documented so Randy's team could maintain it independently
"Bilal was easy to work with and did a great job. Easy to communicate with and make adjustments to the project throughout in order to successfully complete the project for us."
