about

Full Stack Developer in training, self-taught in Artificial Intelligence and LLM-based systems.

I build applied AI projects — Retrieval-Augmented Generation, workflow automation, AI agents and intelligent tools — mostly with Python and TypeScript.

I like real-world problems best: combining software engineering, machine learning and modern tooling into things people actually use.
