Open to junior frontend / full-stack and AI engineering roles

Profile

I study Computer Science and Econometrics at the University of Gdańsk, combining software engineering with statistical and systems thinking.

My work spans production web applications, Cloudflare-based APIs, WordPress commerce, offline-first operational software, and open-source tools for coding agents.

I use Codex, Claude Code, MCP, and OpenAI/Anthropic/Gemini APIs during implementation and debugging, while keeping architecture, verification, and final quality under human review.
