About

Professional summary

I'm a Product Designer with 5+ years of experience, working across iGaming and Fintech with a focus on Design Systems and the practical application of AI in the design workflow.

Day to day, I'm the technical reference for Design Systems: token architecture (from primitives to semantic), component libraries, and per-tenant theme automation — today supporting 80+ screens and 200+ components in production across multi-tenant platforms used in different markets. I have advanced command of Figma (Auto Layout, Variants, Design Tokens) and use Claude, Figma MCP, and Notion MCP daily for research, documentation, and iteration — I'm certified in Claude for Designers by Tera. I've also led hypothesis-driven discovery on payment flows, which brought me closer to the fintech space.

I started my career leading a graphic design team, and that experience still shapes how I work: I negotiate with Engineering and Product with the same ease I use to defend a design decision with data. Complex environments, with priorities shifting fast, are where I do my best work.

I'm always open to trading notes with other designers, PMs, and engineers on Design Systems, AI applied to design, and what it actually looks like to build product in complex environments. If that's your world too, let's talk.
