Builds the unglamorous middle — the schemas, the SLAs, the systems that quietly carry 100K+ daily users and $500K+ in revenue without breaking a sweat. React to Postgres to AWS, the whole stack — shipped, measured, mentored.

01 /A short biography
Not a developer. An architect with opinions.
Fig. A
Five years deep, I’ve been the engineer in the room who asks the awkward questions — the one about the database’s recovery plan, the unowned cron, the silent retry loop. The reward for asking is a system that doesn’t page anyone at three in the morning.
Today I write React, TypeScript and Node by day, study software security and AI-assisted development by night at the University of Turku, and split the in-between mentoring the next batch of engineers. I’ve scaled things to 100K daily users, shipped product worth $500K+, and somehow still find time to win the occasional hackathon.
