Colin Lee is a Principal Mobile Architect with 12 years of experience designing and shipping high-impact mobile apps and SDKs, currently leading mobile architecture at webAI from Saint Paul, MN. He has driven major rewrites and greenfield launches—most notably leading Firefox for Android frontend work at Mozilla and spearheading a Kotlin Multiplatform strategy at Meetup—while also building on-device and on-premise AI mobile integrations in Swift and Kotlin. His hands-on background spans Android system-level work (GeckoView/WebView renderer selection, crash fixes, A/B testing) to build-and-release automation for large apps, and he’s successfully taken products from solo-built betas to acquisition. A pragmatic mentor and remote team leader, he combines deep mobile engineering craft with product-focused delivery and a surprising literary foundation (BA in English) that informs clear technical communication.
