I will integrate chatgpt or claude into your app or website
Dan Warriner
About this gig
act, Next.js, Supabase, PostgreSQL.Adding AI to an app is easy to demo and hard to ship. The demo works, then it meets a rate limit, a timeout, a strange input, or a bill nobody budgeted for.
I build the version that survives contact with real users: streaming responses so it feels fast, conversation memory that does not blow your token budget, retries and graceful failure, and usage metering so you can see what it costs.
WHAT I CAN CONNECT
Claude, ChatGPT, Gemini or Grok, into a React, Next.js, Node, Python or plain web front end. RAG over your own documents when the model needs to know things it was never trained on. Tool and function calling when it needs to actually do something rather than just talk.
WHAT I HAVE BUILT
A multi-persona AI chat platform running on 69 serverless functions with live voice, image generation and token billing. A voice-first CV builder that interviews people in real time.
HOW I WORK
Tell me what you want it to do and where it lives. I will tell you honestly what is realistic before you pay anything. You get working code in your repo, deployed and commented.
Stack: TypeScript, Python, Node, React, Next.js, Supabase.

I build and ship production web and mobile apps. Seven live platforms: a learning platform with Stripe billing and live video, a scheduler that renders video in the cloud, a 3D music visualiser in WebGL, and more.
BSc Computer Science. React, TypeScript, Python, Node, Next.js, Supabase, Firebase, PostgreSQL - plus the parts people forget: auth, payments, admin panels and deploys.
AI when you need it: Claude and OpenAI integrations, agents, MCP servers, voice.
Send me the messy half-built thing and I will tell you honestly what it needs.
