I build ideas that scale.

I’m Tessel. A 22-year-old software engineer and founder who cares about how a product feels—and how it works. I take things from first sketch to real people using them. Everything on this site has been built & designed by me.

A LITTLE ABOUT ME

I like the whole
product problem.

Making an interface feel right. Figuring out the architecture behind it. Shipping, listening, and doing it again.

I’m the founder of Bridge Labs, where I design and build consumer apps and internal tools. My work covers UX/UI, visual asset design, React and TypeScript implementation, APIs, and production operations. I also work with a senior Unity developer on our shared multiplayer codebase.

Previously, I contributed to frontend work at Leads.io and developed apps with LetPeopleWork. I was also invited to a Tools for Humanity / World build week in South Korea, where I placed third in the pitch competition.
