About
Background & experience.
I co-owned Mediashake.fi for years, helping businesses grow through digital marketing. These days I advise them on the side while putting all my energy into building my own products.
I like making things that are genuinely useful. Tool directories, review platforms, whatever the idea is. When I'm not building, I'm up in Finnish Lapland enjoying the quiet or back in southern Finland skating through summer.

Work with me
My focus is on building right now, not taking on new clients. But if something clicks, I'm always happy to talk.
