Hey , I’m Ivan Legchilov

Senior Product & UI designer for games, apps and the web

and all the other design stuff, too

In 6+ years of commercial work I've led a design team on a metaverse that raised $7M, made hundreds of concepts and taken products all the way to launch.
There's more to my design than screens.
Research. Flows. Systems. Motion. Code.
AI is part of my daily routine: a custom platform for research and audits, a system for prototyping and interface design, an AI-native UX/UI flow, and building products myself, with no developers involved.
Based in Poznań --:--, available worldwide. I'm even open to
relocating.
Open to full-time and contract roles.
I don't split design into niches, I'm at home in all of them.
