What I'm looking for

I'm looking to lead and build production iOS products where strong architecture, testing, mentoring, and practical AI engineering workflows improve delivery quality and team effectiveness.

I've led iOS development at Appetiser Apps / All-X, shipping App Store products across e-commerce, lifestyle, health and fitness, and utilities. I build maintainable Swift and SwiftUI applications using MVVM-C, Coordinator patterns, Swift Concurrency, Combine, testing, and production monitoring.

I lead iOS engineers day to day through code reviews, engineering standards, mentoring, technical interviews, and onboarding. I also introduced team practices for Claude Code and Codex, creating reusable agents and versioned skills for planning, testing, reviews, releases, and AI-generated code governance.

Previously, I built real-time chat, video streaming, and calling apps at Ntersol OPC, and cross-platform iOS and Android applications at Leisue Inc. My shipped work includes rainscape, featuring 500+ rain recordings, subscriptions, background playback, and AirPlay.
