At Headphones Inc., I rewrote the application and developed GraphWorks, an in-house headphone measurement visualizer, using React, Next.js, and Node.js.

At INM Audio, I created the company website and a 3D Custom IEM configurator. I also digitized model selection, design, and order requests.

At Dev Protocol, I collaborated on user experiences for products including stakes.social, Clubs, and Initto. I created the Hashi design system and Clubs UI.

I founded and co-created GrowStocks, a companion app for Growtopia, and developed its price index and marketplace features. I created its Gaia design system, and the app reached over 10k daily unique users at its 2020 peak.
