01 / ABOUT

Code with purpose.
Design with empathy.

I build the interfaces people actually use — game platforms, dashboards and business tools.

Since 2021 I have worked at KOS Design, shipping Web3 game platforms such as Nakamoto Games and Outlanders together with their admin back offices, mostly in Next.js. Alongside that I freelanced for Planet X Technology on business platforms and service-management systems. I take a feature from Figma to production, care about the details, and pick up new tools quickly.
