Resume / Software engineering / Poland

I build software with AI as part of the engineering system.

Junior Software Engineer — AI-Native Product Development

Software engineer who turns product ideas into working web software using agentic coding workflows as a daily development environment. Strongest in practical AI-assisted implementation, debugging, tool orchestration, and deliberate human review.

Open to junior AI engineering and full-stack product roles

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, OpenCode, Pi, and MCP-based tooling during implementation and debugging, while keeping architecture, verification, and final quality under human review.
