What I'm looking for

I'm looking to build reliable mobile products and tackle complex architecture, networking, performance, and legacy-code challenges with collaborative product and engineering teams.

I've spent over 20 years building software across native iOS, distributed systems, system integration, and low-level C/C++ development. I focus on solving difficult production problems and making architecture decisions that reduce risk.

I migrated a legacy Objective-C/Linphone application to Swift, SwiftUI, and WebRTC, helping define a reliable real-time communication architecture under challenging network conditions. I’ve also delivered iOS features, managed App Store releases, and aligned engineering work with product, QA, and Android teams.

I’ve built BLE-based mobile payment prototypes, a medical information system, scalable multimedia experiences, and offline music functionality. Earlier, I led QuarkXPress XTension development in C and managed a small engineering team across concurrent product tracks.
