About

Senior iOS Engineer with 8+ years of experience architecting and shipping production apps across fintech, health & wearables, automotive telemetry, and social media. I've led iOS teams end-to-end — architecture, mentoring, code review — while staying hands-on with the hard problems: real-time Bluetooth health data sync, lending and payment flows, vehicle telemetry, and media processing pipelines.

Currently focused on Swift 6 strict concurrency and protocol-oriented architecture, and maintaining a set of open-source libraries used in production apps.

I also work AI-augmented: over the past months my daily workflow is built around agentic coding with Claude, Codex, and Cursor — delegating implementation to agents while I own the architecture, constraints, and code review. Not vibe coding; engineering with leverage.
