02 / About
Designer by trade, builder by habit.
I've spent 15+ years designing digital products for agencies, startups, and enterprise teams, from a consultant platform at 7N to design systems at Egnyte, Zonal, and nexos.ai.
Lately I also build what I design. With Cursor and Claude Code I take a product from Figma to a working, deployed app. Digna, a telemedicine app for menopause care, went from brief to production in three days. I designed and built all 25 screens.
For clients, that means a product you can click, test with users, and show to investors, instead of a static Figma file waiting for a developer.
03 / Tinkering
Side projects, built to scratch an itch.
All on GitHub ↗- TypeScriptfigma-design-system-agent ↗AI agent toolkit that turns Figma files into working design systems and responsive prototypes, and generates Figma designs back from code. Runs in Claude Code, Cursor, Copilot, and other MCP clients.Updated Sep 2026
- TypeScriptpayload-board ↗Desktop app that launches a set of apps in order, shows their live status, and closes them all with one click. Built for simracing sessions.Updated Sep 2026

05 / Services
How I can help.
Product design
End-to-end UX and UI for web and mobile products: research, flows, prototypes, and polished interfaces ready for development.
Design systems
Component libraries and documentation that designers and engineers share. I owned design systems at Egnyte, Zonal, and nexos.ai.
Design + build
When you need an MVP or a clickable product fast, I design it, then vibe-code it into a working web app you can deploy, test, and iterate on.
06 / Contact
