I'm a product designer based in Seattle, Washington and founder of SMPLPXLS, a software development and publishing company. For most of my career, the line between "designer" and "engineer" was a wall I respectfully waved at from my side—I'd hand off Figma files and work with engineers to build somewhere I couldn't quite see. That wall is gone. With the current generation of AI tools, I ship production-ready full-stack work myself, and the loop from idea to live product has collapsed from months and weeks to days. Some recent products I've designed and built from the ground up include:

• SMPLNVST—a cross-platform paper trading app with real-time market data from Massive.com and subscription infrastructure from RevenueCat. TypeScript monorepo, React + Tailwind on web, React Native on iOS, Supabase Edge Functions, deployed on push to remote main onto Cloudflare Pages. Design system, business logic, infrastructure—all mine.
• Vector Art Generator—a free, browser-based tool for making interactive vector art and animated vector backgrounds. Every piece is a motion-inspired WebGL scene you can tune live and export as standalone TypeScript—ready to drop straight into any web project.

In the past year, as the founding designer at Tonkotsu AI, I have also designed and shipped two products and their marketing materials end to end:

• Tonkotsu IDE—a natural-language IDE for macOS and Windows. Describe what you want to build; the system plans it as PR-sized tasks; AI agents work them in parallel; you review diffs and ship.
• Handle Studio—a macOS app that turns a running web app into a working canvas. Designers inspect any element, edit styles directly, and route precise changes through an AI coding agent.

Before Tonkotsu, I was a Principal Product Designer at Meta, where I led design on Marketplace and Shops for 5 years. Before that: Amazon (Fire TV, Echo Show, Echo Spot), Hulu (the 2012 hulu.com redesign), Facebook Seattle (first full-time designer in the office; shipped Save for Later and Audience Network), and almost six years at Teague designing the future of hardware-meets-software experiences for Microsoft, HP, and Panasonic. I believe that designing with and for AI is its own craft. A few things I care about: taste matters, but specificity matters equally, prototypes settle arguments, the best teams are cross-functional, and my architecture school background (Georgia Tech, MIT) still shapes how I think about systems.
