Zac Hamann

Full-Stack Software Engineer

I’m a software developer at an investment advisory firm, where I started as an intern in 2021 and now own the firm’s software platform. I build and run internal and client-facing applications with TypeScript, React, Next.js, SQL, and Azure. Outside of work, I ship my own web and iOS products, including RaceThere, a race directory used by 1,000+ runners a week.
