I'm Marcin (22) a developer based in the Poland, building real products while transitioning into software engineering full-time.

I'm the founder of HCK_Labs and the solo developer behind two active projects:

PC Workman, a Python desktop app for real-time system monitoring with AI diagnostics, fan control, and a persistent SQLite stats engine.

680+ hours, 4 complete rebuilds, shipped as a standalone .exe.

GuideAI, a SaaS platform that turns any PDF manual into an AI assistant accessible via QR code.

Built with React + Supabase. Authentication, dashboard, device management, all working.

I build in public, document everything (with articles), and ship instead of waiting for perfect conditions.

Open to junior developer roles in Python, React, or anything where I can contribute and keep growing fast.
