Roosa · Finland · Open to AI, backend, and software engineering roles

AI & Software
Engineer

I ship reliable AI workflows and secure Python backends - designed, tested, deployed, and documented end to end.

I build secure software, AI workflows, and real-time creative tools. At Assembly Summer 2026 I shipped two demoscene projects and placed 2nd in the Fix It Competition with SceneStart. I have been active in the demoscene as an organizer since 2014, and now also as a creator and competitor.
