Product / AI Engineer

About Me

I build product interfaces in React, React Native and Next.js, and connect them with the AI tooling that is transforming development.

At Gyoza I led the implementation of Wetour (a Next.js community with an SEO focus) and Turbowash (a React Native app controlling laundry machines: payments, loyalty, and remote activation), alongside contributing to Goiko.

My work is grounded in scalable UI architecture and in state and async data management with Zustand and TanStack Query.

In little over a year I went from pure frontend engineering to shipping design-context-bridge: my own MCP server in production, compatible with Cursor, Claude Code, and Windsurf, giving AI agents real design context from Figma.

When a tool I need doesn't exist, I build it.
