Project details
Want to add AI to your existing product? That's exactly what I do.
I integrate OpenAI (GPT-4) and Anthropic (Claude) into web apps — chatbots, smart search, content generation, recommendations, and RAG systems — cleanly wired into your existing frontend and backend.
What you get:
Production-ready AI integration, not a demo
Streaming responses, function calling, structured outputs
Clean, documented code you can build on
Works with React, Next.js, Angular, .NET Core, or Node.js
I'm a full-stack developer with 5+ years of experience and a track record of shipping AI features to real users — not experiments. I'll tell you honestly what's realistic for your budget and timeline.
Message me before ordering so I can scope your project accurately and recommend the right package.

React App Is Slow & Crashing Under Load — Need Performance Fix & Stabilization
Usama diagnosed and fixed the performance problems in our React app that had been slowing us down for months. Page loads went from 5–8 seconds down to under 2, the dashboard freezing on large lists is completely gone, and the random production crashes have stopped. What stood out most was that he actually found the root causes instead of applying band-aids — and he documented everything so our team understands what was wrong. Communication was clear and jargon-free, updates were consistent, and he delivered on time. We've already started him on new features. Highly recommend.

Usama did excellent work on our AI-integrated web app. Built a clean React/Next.js front-end and a solid Node back-end, and handled the OpenAI and Claude integration smoothly. Communication was clear and consistent, deadlines were met, and the quality was high throughout. Highly recommend - would hire again.
