What I'm looking for

I am looking for a hands-on senior/principal iOS role where I can lead architecture, mentor engineers, and drive end-to-end delivery in a collaborative, product-focused team.

I am a Staff/Principal iOS engineer with 10+ years shipping production iOS apps across health, media, social, education, and finance products. I specialize in modern iOS development using Swift, SwiftUI, Combine, and Swift Concurrency, and I take ownership across architecture, implementation, QA, release delivery, and production support.

I've led and delivered apps both as a sole iOS engineer and as a senior technical leader, establishing architecture standards, modular designs, and CI/CD-backed release workflows. I drive pragmatic engineering practices—modularization, dependency injection, and SOLID principles—to enable predictable delivery and maintainability.

As a hands-on engineer and mentor, I have established SwiftUI-first architectures, practical testing baselines, and release reliability processes, while contributing to hiring and cross-functional collaboration. Notable outcomes include building Live Timecode Notes from scratch, executing frequent reliable releases, and shipping initial apps and major migrations to SwiftUI.

I am product-focused and delivery-oriented, with experience defining API contracts, implementing offline-first sync, and ensuring production stability. I bring a balance of deep technical expertise and leadership to help teams ship quality mobile experiences at scale.
