I recently built and shipped core AI infrastructure for Chaaty.AI, a multi-model AI chat platform where users compare outputs from Claude, GPT, Gemini, Perplexity, Grok and more side-by-side.

What I bring to your project:

Direct integration with Anthropic and OpenAI APIs (including raw HTTP implementations for advanced features like prompt caching, which cut response costs and latency significantly)

Multi-provider architecture — wiring up several AI models into one clean interface

Laravel backend development — from webhook handling to job queues

Stripe payment integration, including subscription billing, trial logic, failed-payment recovery, and dispute handling

Debugging and fixing production issues under real user load

React/TypeScript frontends that are fast, clean, and built to convert

If you're building an AI-powered SaaS product and need someone who can handle the AI integration, the backend logic, and the payment flow — not just one piece — let's talk.
