About
I'm a Staff Android engineer in Oakland. Over ten years I've shipped production apps for connected hardware, healthcare, construction, and fintech — including a patented BLE communication layer built on Kotlin coroutines and a server-driven UI system in Jetpack Compose. Since 2020 I've led Kotlin Multiplatform architecture sharing real code across iOS and Android, and for the past two years I've built an AI product end to end, working daily with LLM pipelines and agentic tools like Claude Code. I'm looking for a staff-level role where deep Android craft and cross-platform architecture move a product that matters.
