ABOUT

The day job.

I build product end to end — the React in front, the TypeScript and Postgres behind it, and lately a lot of AI in the middle. Six-plus years of it, across a startup conference, an AI search company and now Lovable, where I'm on the team turning prompts into running apps.

I like owning a thing end to end, unglamorous parts included, and I'd rather fix the root cause than add a retry.

WORK

Things I've built that answer.

From a startup conference's entire stack, to AI search, to the app builder everyone is talking about. Also printf, in C, from scratch.

Lovable

Full-stack engineering at the AI app builder that goes from a prompt to a running product. I work on the parts that have to be fast, correct and invisible when they work — and loudly obvious when they don't.

Realm

AI-powered workplace search: one query across every tool a company uses. Retrieval, ranking, the connectors that keep the index honest, and the box people actually type into.

German learning app

University of Helsinki software-engineering project: an open-source web app for learning German, built by a student team in sprints with a real customer. I reviewed 110 pull requests and landed 78 of my own.

The world's leading startup event. I joined as a web developer and left as Chief Product & Technology Officer, owning the event platform, matchmaking and the apps thirteen thousand people depend on for two days a year — with no second take if they fall over.

ft_printf & fillit

C from scratch at Hive Helsinki (42 network): a full printf reimplementation and a backtracking solver that packs Tetris pieces into the smallest square. No libc, no leaks, no mercy from the grader.
