What I'm looking for

I’m seeking senior engineering roles focused on cross-platform desktop development, impactful product ownership, strong engineering practices, and opportunities to mentor while working in teams that value quality and delivery.

I am a software engineer with 18+ years in IT and 15+ years focused on software development, delivering robust desktop and cross-platform applications for Windows, macOS and mobile environments.

I have driven meaningful product improvements, including boosting GUI performance by 30% and reducing crash rates through targeted optimizations in large legacy codebases.

I’ve built and maintained products end-to-end—from Flow Web Browser and AltVPN client to MindManager and Soda PDF—mentoring teams and implementing CI/CD, automation testing, and native platform integrations.

I am customer-focused, deadline-oriented and stress-resistant, with deep experience in C++, C#, Objective-C, Python, automation (Selenium, Microsoft UI Automation) and modern toolchains, ready to contribute to complex, fast-paced engineering teams.
