Android Engineer · Open Source Author
Etienne Lawlor.
Senior Android Engineer.
I build high-quality Android apps and open-source tools used by thousands of developers. Currently building for creators at Kajabi.
About Me
I'm a Senior Android Engineer with 10+ years of experience building mobile products used by millions of people. I've had the privilege of working at companies like Kajabi, DoorDash, ClassDojo, and Headspace — each giving me deep experience with large-scale Android codebases, platform APIs, and cross-functional product teams.
Outside of my day job, I maintain several open-source Android libraries with 1,000+ combined GitHub stars, contribute technical articles on Medium, and build surf apps for my local community in Hawaii.
I care deeply about code quality, developer experience, and shipping features that make a real difference to users. When I'm not at a keyboard, you'll find me surfing, playing tennis, or out on the golf course.
