You will get custom AI LLM, RAG pipelines into your app
Project details
Want to add AI to your existing app but don't want to rely on bloated, slow frameworks? I build custom, lightweight AI integrations using Python, AWS Bedrock, and OpenAI APIs.
I specialize in building RAG (Retrieval-Augmented Generation) pipelines that allow your AI to securely query your company's private data, and agentic workflows that actually get work done. With 100% Job Success and years of experience building production SaaS platforms, I don't just write prompt scripts—I engineer secure, scalable AI infrastructure.
Whether you need a simple ChatGPT integration for your users, or a complex multi-agent system that queries your internal databases, I deliver clean, documented Python code that handles real traffic.
Send me a message with your AI idea, and I will tell you exactly how we can engineer it.

AI SaaS Developer (Python, Next.js & Perplexity AI) – Performance Optimization & Bug Fixes
Excellent developer with strong Python and Next.js skills. He investigated latency and streaming issues, implemented an effective solution, and ensured everything was thoroughly tested before delivery. Professional, responsive, and easy to work with.

Full stack React / Python Dev with experience with GCS
Usman provided me with some brilliant advice on how to sort out an issue that was far bigger in scope than imagined, hes a top level dev - and a great person too. Easy to talk with, extremely knowledgeable and his communication skills are excellent which was very helpful as I am not very technical. If you need someone serious for a big project - he's the sort of guy who can do it all at scale. Thanks Usman.

Job Success
Lahore, Pakistan - 4:12 pm local time
100% Job Success | 598+ Upwork Hours | 22 Jobs | My three longest contracts ran 2 to 4.5 years each. Clients hire me to build, deploy, and maintain their core products.
MY FULL STACK EXPERTISE:
âś… Backend Development & APIs: Python, Django, FastAPI, REST & GraphQL, PostgreSQL, MongoDB, Redis, async task orchestration (Celery)
âś… Frontend Development: React, Next.js, TypeScript, React Native (cross-platform mobile when needed)
âś… AWS & DevOps: ECS Fargate, ECR, ALB, Route 53, SES, Lambda, Terraform (IaC), Docker, CI/CD. I write the code, deploy it, secure it, and keep it running under production load.
âś… Payments & Fintech: Stripe Billing + Stripe Connect (marketplaces, subscriptions, payouts), money-correctness auditing
✅ AI Integration: LLM-powered features with AWS Bedrock, Anthropic/OpenAI APIs, RAG pipelines, and agentic workflows built directly on boto3—no framework bloat.
🚀 RECENT FULL STACK WORK:
• Built a two-sided contractor marketplace (Django backend + React frontend + Stripe Connect + AWS ECS Fargate).
• Developed a fintech bidding and negotiation platform taken from zero to production.
• Engineered real-time IoT consignment tracking systems with React Native dashboards.
How I work: Clear communication, honest estimates, and I flag problems before they become expensive. I treat your infrastructure bill and your deadline like they're mine.
If your project needs a Full Stack developer who can own the database, the API, the UI, and the deployment—send me a message. I respond within immediately.
Steps for completing your project
After purchasing the project, send requirements so Usman can start the project.
Delivery time starts when Usman receives requirements from you.
Usman works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & Use Case Planning
We define your AI use case, identify the right LLM (OpenAI, Anthropic, etc.), and plan the data pipeline or agent workflow.
Data Processing & Vector DB Setup
For RAG projects, I ingest your documents, chunk the data, and set up the vector database (pgvector, Pinecone) for secure semantic retrieval.
