Luke Patterson

I build apps, and I play guitar. I’m the founder of Tahanan, where Filipinos around the world learn Tagalog, and Xylo Software, the studio behind it.

Before that I spent nine years as a software engineer at DraftKings, Focused Labs, Mandolin, and Hyland. I’m Fil-Am, I live in Cleveland, and I’m a cat dad of three.

Tahanan

Founder

Tahanan means home. It’s the Tagalog app I wish I’d had growing up: lessons built around family, practice calls you take out loud, and real coaches from the Philippines. It’s rated 4.7 on the App Store, it’s profitable, and it’s growing fast.

Xylo Software

Founder

My independent app studio. I lead a small remote team of talented, passionate people, and together we build consumer apps for very different audiences: Tahanan for heritage learners, MobilityLibrary for anyone who wants to move better, Backlined for touring bands, and Tigris for private calorie tracking.

Ten years of shipping software

Native iOS in Swift, SwiftUI, and TCA. React Native, React, Next.js, and Node on the web. Kotlin, Rails, and Postgres when the backend needs it. I’ve also run scrum teams and mentored engineers.

Who Saved Who

For six years I played lead guitar and sang backup in Who Saved Who, an indie rock band from Cleveland. We put out a full-length album, Sharing the Daytime Moon, plus a run of EPs and singles on every streaming platform, and we toured all over the Midwest.

I’ve stepped away from the band, but music is still a big part of who I am.

“Every Waking Passing Moment,” the music video I’m proudest of.
