About

Design that survives implementation

I design software products across the full lifecycle. My background sits at the intersection of design and front-end engineering, which lets me carry an idea from a rough concept all the way to shipped, detail-perfect interfaces without losing intent along the way.

Beyond design, I've led teams as a product manager and team lead — so I'm comfortable owning outcomes end to end, not just the mockup.

Today I work as a product designer at BPMobile (AIBY Group). Alongside that, I build my own consumer mobile apps with the help of AI. Previously I was Principal Designer on a top-charting AI assistant with 100M+ downloads that won a Lovie Award in 2024 for Best User Experience.

Alongside product work, I build and maintain Veritheme — an open-source design system built on a single theme.json that keeps Figma, CSS, and AI tools in perfect sync. I also mentor designers and create educational content through uxui.one and my YouTube channel.

A background in front-end development lets me make design decisions that survive implementation intact.
