I’m a freelance software developer.

I take on web apps, backend systems, and mobile apps for iOS and Android. The apps below are mine — proof that I ship.

Most of it is web applications and the systems behind them: front ends, APIs, databases, and integrations between things that don’t want to talk to each other. I also build native mobile apps for iOS and Android, start to finish.

If you have a project in mind, email jake@jakehaas.com. Two or three lines about it is plenty to start.

about/

I’ve been building software professionally since 2010. Along the way I’ve been a full-stack engineer, a backend systems administrator, and a solutions architect, plus a few other titles in between. Most of that was on staff; these days I freelance.

Having done all of those jobs, I’m comfortable owning a project end to end instead of just one slice of it. That’s usually why clients bring me in.

The apps on this site are my own, built on the side. If one gives you trouble, or you think of something it should do, email jake@jakehaas.com.
