Joshua Hamm_

I build full-stack web apps, backend APIs, and games — across Java, C#, TypeScript, and Python. Comfortable everywhere from database schemas to render loops.

About.

I'm Joshua Hamm, a software engineer who works across the entire stack. I write production web applications, design and ship REST/GraphQL APIs, build desktop and game experiences, and enjoy the kind of problems that span multiple layers at once.

My day-to-day spans Java, C#, TypeScript, and Python. I care about clean architecture, reliable systems, and interfaces that feel fast and intentional.

When I'm off the clock I build small games and creative experiments — you can play three of them right here in the browser.
