What I'm looking for

I'm looking to build reliable full-stack and AI-powered applications, contribute to practical products, and keep growing through hands-on development, debugging, and collaboration with experienced engineers.

I built a real-time voice AI assistant for restaurant reservations using WebRTC VAD, Whisper ASR, an LLM, Piper TTS, and PostgreSQL-backed reservation tools. I designed deterministic conversation flows, rule-based entity extraction, validation, error recovery, and multi-turn corrections to keep reservations reliable.

At Nexxon, I developed a Node.js and React application for searching, comparing, and purchasing tyres, while optimizing its relational database and debugging performance issues. At Quantic Lab, I tested PC, PlayStation 5, Xbox, and Nintendo Switch 2 builds, documented defects, ran regression testing, and worked with developers to improve build stability.
