Making useful thingswith code & curiosity.

I’m Kirk Koster. I build software and practical tools, and I make room for games, writing, and music along the way.

02 / How I work

My path through QA, QA management, and development gave me a practical view of the whole product: how it works, how it fails, and how people use it.

I like turning uncertain ideas into systems that can be understood, tested, and improved.

03 / Beyond software

Game development, writing, and music are part of how I explore ideas. This space will grow as work is ready to share.
