ABOUT ME
Technical Architect | Senior Mobile Application Engineer
Technical Architect | Senior Mobile Application Engineer

Mobile app architect with 19 years of industry experience and 14+ years building iOS \Android applications: from greenfield architecture to rescuing legacy codebases. I've led teams of 15+ developers, shipped apps for high-profile clients, and specialize in turning complex requirements into maintainable, well-tested Swift, Kotlin, Java, C\C++ and Objective-C code.

My technical foundation runs deep: memory management, multi-threading, comprehensive Unit and UI testing, and full project lifecycle ownership from conception to App Store deployment. I've also worked extensively with C/C++ and C# on Windows platforms, and apply Python and JavaScript where they fit the job.

As a team leader since 2013, I've grown teams, built personalized developer growth plans, and helped multiple engineers advance to senior and tech lead roles. I bring the same rigor to people as I do to code.

I'm known for modernizing development workflows, driving cross-team collaboration, and delivering under pressure without sacrificing quality.

Eugene has become an integral part of our development process. He successfully resolved several complex state management and concurrency issues with SwiftData. His proactive approach and research-driven work ethic have been invaluable in refining our app development. We highly recommend Eugene—he is a true asset in building reliable iOS software solutions.

Eugene resolved quickly and efficiently an issue that had been causing me problems for days. He also introduced me to a good browser for looking at SQL Lite databases on the phone, and showed me several things in XCode that should make my life easier going forward. Very nice and well spoken mentor who really knows his stuff!
