What I'm looking for

I'm seeking a Senior or Lead C++ role at a global product company, preferably remote worldwide or with relocation, where I can build high-performance cross-platform systems and lead engineering teams.

I've architected and led TrustPlugin, a native C++17/Qt6 cryptographic SDK deployed across a national-scale government-services platform and a major financial institution. I built support for seven cryptographic providers and three hardware-token types, delivered 92% shared cross-platform code, cut load time from 8 seconds to 1.2 seconds, and increased throughput fourfold.

I've grown an engineering team from 1 to 10, introduced Agile practices, mentored junior engineers, and conducted 500+ code reviews. More recently, I've independently built a C++23/Qt6 disk-analysis tool with offline AI recommendations, Flutter/Dart mobile apps, and Chrome/Safari browser extensions.
