I will integrate chatgpt, claude or gemini API into your web app


About this gig
Want AI features in your app that actually work in production -
not just a demo?
I'm a Full-Stack Developer specializing in AI API integration.
I connect OpenAI, Claude, and Gemini to real applications - building
chatbots, automations, and AI-powered features that handle real
traffic, real data, and real edge cases.
WHAT I BUILD:
Custom AI chatbots with conversation memory
RAG systems - AI that answers based on YOUR data, not generic info
AI-powered automations and workflows
Backend integration for OpenAI / Claude / Gemini APIs
Production-ready code with proper error handling
TECH STACK:
TypeScript JavaScript Python (FastAPI) PHP Node.js
PostgreSQL MongoDB REST APIs
WHY WORK WITH ME:
I write real, scalable backend code - not no-code workarounds
I understand architecture, not just "API calls"
Clear communication, no technical jargon dump
Support included after delivery on every package
HOW IT WORKS:
1. Send me your project details (even rough ideas work)
2. I respond with a clear technical plan and accurate quote
3. You get working, tested, documented code - ready to deploy

FAQ
I only have a rough idea, not a full spec - can you still help?
Yes. Describe what you want to achieve, and I'll propose a clear technical solution and quote.
Which AI model should I use - OpenAI, Claude, or Gemini?
Depends on your use case. I'll recommend the right fit based on your budget and requirements.
Can you add AI to my existing app, or does it need to be built from scratch?
Both. I can integrate into your existing codebase or build a new module from the ground up.
Are API costs (OpenAI, Claude) included in your price?
No - API usage costs are billed separately by the provider based on usage, typically $5-50/month depending on scale. My fee covers implementation, not the ongoing API subscription.
Do you offer support after delivery?
Yes, every package includes a support period for fixes and questions (3-14 days depending on package).
