Who I am?

For nearly a decade, my career has been driven by a passion for solving complex backend challenges and building the robust infrastructure that powers innovative technology. My focus lies in the demanding worlds of FinTech and blockchain, where security, performance, and scalability are paramount. My journey has taken me from deep, hands-on systems programming—optimizing the Linux kernel and building secure software delivery pipelines—to leading talented teams as a CTO. I thrive on architecting systems from the ground up, whether it's a P2P cryptocurrency exchange, a secure crypto-to-fiat payment gateway, or an award-winning AI installation. I lead by example, contributing directly to the codebase while managing the full IT and DevOps lifecycle. I believe in creating environments where engineers can do their best work. I am always seeking ambitious challenges where I can contribute to building impactful technology and help a talented team succeed.
