ABOUT

I’m past the “just make it work” phase.

My Applied Informatics studies are complete and I’m currently waiting to receive my diploma. The projects I care about most are the ones that force me to think across frontend state, backend rules, database structure and the full user flow.

I like building things that are easy to reason about, easy to test and designed to grow without turning into a mess.
