About this gig
-MESSAGE ME BEFORE ORDERING-
Want to add AI to your app, but don't know where to start, or tried and it broke everything?
I integrate AI APIs into your existing web app. Not a chatbot widget. Real backend integration with your data, your logic, your users.
I've worked with OpenAI, Claude, Gemini, and OpenRouter. I recommend the right model for
your use case, not just the most popular one.
WHAT I BUILD
- AI chatbots trained on your own data
- Text summarization and content generation
- AI-powered search for your app
- Auto classification, tagging, and moderation
- Streaming responses with real-time UI
- Rate limiting, token tracking, cost controls
- Multi-model routing via OpenRouter
WORKS WITH

Full-stack developer with 4+ years building web apps, SaaS platforms, REST APIs, and AI integrations, from first commit to production.
I work across the full stack: React, Next.js, NestJS, Node.js, PostgreSQL, Prisma, and BullMQ. Projects range from MVPs and internal tools to AI-powered backends and mobile apps with React Native.
I also take on broken or unstable codebases, including AI-generated ones, and get them to a state you can actually ship.
Clean architecture. Reliable delivery. 5.0 rating across every order.

FAQ
Do I need an OpenAI or Claude account?
Yes, you'll need your own API key and account. I'll tell you exactly which plan you need. Most projects start on the free or basic tier.
Can you integrate AI into an app that's already built?
That's exactly what I specialise in. Send me your stack, and I'll confirm within a few hours.
Which AI model do you recommend?
Depends on your use case and budget. I'll advise the right model after reviewing your requirements, that's part of the service.
Will you handle API costs?
You pay your own API provider directly. I built the integration with cost controls so you never get a surprise bill.
What if I want to switch models later?
I build integrations to be model-agnostic where possible, so switching from GPT-4 to Claude or Gemini later is straightforward.
