CTO at Clevoy · software engineer in Seinäjoki, Finland

Juha Ala-Rantala

I build product software from rough idea to working system.

Currently leading product and engineering at Clevoy. Before that: industrial software, AI research, local-model prototypes, and a long trail of side projects that usually start with "what if this existed?"

Say hello, share an idea, or connect.

I am always happy to hear from people who build things, study technology, work with AI, or just want to trade ideas. Email works best; LinkedIn is good too. If you are in Seinäjoki, coffee or a burger also works.
