For ~20 years I've made my living from random projects I put online. I launch many experiments, then continue if they seem promising.

The current projects are a baby naming site and games about finding cats. Before those my main project was Candy Japan, which I turned off because of COVID postal restrictions, but might restart later.

Personal life

Finnish, but have been living in Japan for 10+ years. Came for exchange study initially, now settled in Tokushima with wife and son.

Mini résumé

Master's in computer science from Tampere University, with a minor in Japanese from ICU. Also worked several years at Tampere University and other places as a programmer.


I spend my free time practicing colemak, swimming (~2km / week), gaming, and reading. Took Japanese study pretty seriously, until I hit a plateau and haven't continued since 2021.
