What I'm looking for

I seek roles where I can lead technical initiatives, work on cross-platform and security-focused systems, mentor engineers, and contribute to robust, well-documented production software in a collaborative environment.

I am a senior software engineer with extensive experience building cross-platform desktop and backend systems, leading teams, and delivering secure, high-performance applications. I have led technical initiatives, mentored developers, and produced comprehensive technical documentation to support long-term maintenance and onboarding.

My hands-on background spans C++, C#, Objective-C, Rust, Go and multiple OS targets (Windows, Linux, macOS). I have driven projects including batch banking processes, file compression and manager tools, a cloud media library, a confidential email client, and multithreaded download modules, consistently focusing on robustness and user experience.

I bring strong organization, responsibility, and a continual interest in emerging technologies; I prioritize clear design, test-driven development, and secure implementations (OpenPGP, OpenSSL) to deliver production-ready software and improve team productivity.
