Tim Demars

Full Stack Developer

I build accessible, performant web applications from database to UI.

01.About Me

I'm a full stack developer with 9 years of experience building products across the entire stack — from database design and API architecture to polished, responsive frontends. I care about clean code, thoughtful UX, and shipping software that holds up in production.

Currently, I'm focused on building scalable web applications with modern JavaScript ecosystems. I enjoy working at the intersection of product and engineering, turning complex requirements into maintainable systems that users actually love.

When I'm not coding, you'll find me exploring new tech, contributing to open source, or refining side projects that push my skills further.
