I build products end-to-end — from requirements and architecture through to production deployment. Frontend on React and Next.js, backend on Node.js or Python, AI integrations on top of LLM APIs, deployment on Vercel and Railway.
Most of my commercial work sits in three areas: Telegram automation, AI-integrated dashboards, and data extraction platforms. I've also owned the non-code side — writing technical specs, scoping and pricing projects, and running client communication directly.

I use Claude and Copilot for boilerplate and for moving through unfamiliar APIs. Architecture, review and debugging stay with me. Pick any repository here and I'll walk you through why it's built that way and what I'd change — that's the part worth judging.
