Product designer who builds.

I take products from a blank Figma file to something people can click: brands, design systems, dashboards, and working front ends I build with AI.From a blank Figma file to something people can click.

How I work

One person from idea to shipped. Fewer handoffs, less lost in translation.

Frame

Start from the problem, not the screen. I talk to the people who sell, support and use the product before opening Figma.

Systemise

Foundations, components and docs, so the next screen ships faster than the last one.

Build

I vibe code with AI, so ideas become working prototypes and tools, not just mockups. With a dev team, I hand off specs they can build from.

Iterate

Ship, watch how people use it, refine. The design isn't done at launch.

Side B

What I make when nobody's asking. Music, games and small oracles I build to learn.

Electronic music

Original tracks, mostly Drum & Bass, but also whatever I feel like making.

Listen

Brick builder

A browser-based 3D building game with real pieces, searchable, with realistic connections.

Hobby project

MP Vote Oracle

A SEDA oracle program that returns how a Canadian MP voted, from openparliament.ca.

Learning project

Earlier work

AlchemistWebsite Design - Blockchain Community
NFTradeProduct Concept and Design - NFT Escrow
BitBotzPersonal project - Generative NFTs
TartareApp design - DeFi Tools

I design it,
then make it real.

I taught myself UI after audio engineering school, a sales job and a startup of my own. I went from junior UI designer to product designer in three months, then spent two years at SEDA, growing into Head of Product.

I learned the basics at a coding bootcamp, and for the past year I've built with AI: front ends, internal tools, small oracles. I'm not a career engineer. AI lets me get a working version in front of people fast, and talk to developers in their language.

I'm happiest where design, data and code meet. Off the clock I produce electronic music.
