Software engineer for connected devices. I help hardware teams ship software that pairs reliably, syncs accurately and updates safely. Patented Bluetooth security co-inventor with six years leading mobile and platform work for consumer and regulated medical devices, built on TDD, clean architecture and predictable delivery. What I bring: - Device connectivity: Bluetooth LE/GATT and Wi-Fi devices, pairing and provisioning, background sync and offline-first data, with direct work alongside firmware teams. I'm a co-inventor on U.S. Patent No. 12,652,273, covering encryption of health data from wearable medical devices. - Apps and backends: Swift/SwiftUI, Kotlin Multiplatform and Android apps, with server-side Swift, Python and AWS behind them. - Delivery systems: verification and release automation that lets teams ship without armies of manual QA. I architected an autonomous verification system projected to take a release process from roughly 10 weeks and 4-5 engineers down to about 2 weeks for a single engineer. - AI-assisted delivery: I use multi-agent workflows and AI-assisted pipelines on my own work, which is why small, well-scoped projects ship in days instead of weeks. - Leadership: I've hired, built, and led software teams across mobile, backend and web. How I work: fixed-scope milestones with a clear deliverable, from a one-week architecture review or BLE audit to a full build. I also work in Mandarin, including technical specs and manufacturer communication.
