What I'm looking for

I seek senior engineering roles focusing on iOS/macOS, security-hardened SDKs, and remote team leadership with opportunities to drive stability, performance, and cross-team delivery.

I am a Lead iOS Engineer with 8+ years building high-quality iOS and macOS software, fluent in Swift and Objective-C and experienced across full app lifecycles.

I specialize in performance optimization, networking (TCP/UDP, custom protocols), security hardening, and CI/CD, and I have led remote, cross-timezone technical delivery and SDK development.

Notable achievements include building stable Mac utilities from scratch, modifying open-source desktop code to add end-to-end encryption, and designing custom TCP protocols and multi-region release pipelines to improve stability and iteration speed.
