Let's build
something that lasts.
Currently freelancing as a Full-Stack & GenAI Developer — most recently shipping platform features at YOTSYSTEM (Jan–Jul 2026). Open to remote mid-level full-stack roles on EU product teams.
I'm most excited by product teams shipping real features end to end: React + Node.js, clean TypeScript, and a GenAI / LLM layer that actually earns its keep. If that sounds like the team you're building, let's talk.
