The Tiny Tiger Full-Stack Developer

Kamil Michalak

I'm a full-stack developer in Copenhagen. For eleven years I built and looked after web platforms, mobile apps and CMS systems β€” from the first database schema to the server they run on. JavaScript end to end. Lately, AI tooling is part of my everyday workflow β€” used carefully, tested properly.

How I work with AI

AI is part of my normal workflow β€” not a magic button. I run Claude-based agents for code review, tests, translations and refactoring. The bar is the same for everything that lands: typed, tested, reviewed.

M1

Agents with narrow jobs

Small, specialised agents β€” review, security checks, translation β€” each with limited tools and a defined output.

M2

Knowledge that sticks

Conventions and lessons are written down where the AI can reuse them β€” quality doesn't reset between sessions.

M3

Tests keep it honest

AI-written code goes through the same pipeline as mine. If it isn't tested, it doesn't ship.

This site was built that way too.

There's also a person behind this β€” motorcycles, cooking and VR galleries built for family.
