Kes Walker

Android Engineer & Founder
Started as an apprentice at 18. Within 5 years, I'd shipped features for the UK's #1 betting app, solo-built 9 Android apps on the side, and gone full-time on my own startup. Now I run Explorer Innovations, building products across Android, iOS, and web. Open to anything interesting.
