About Me

I am the type of person who tries to learn more each day and from each project. I like to solve problems, understand their root cause, and find the best way to address them. My background covers both software development and cyber security, bridging hands-on coding with infrastructure and security operations — including managing SIEM platforms such as Google SecOps and Exabeam. Outside of work, I administrate my own Linux server (Incus + Podman + Caddy), maintain claude-sandbox (an open-source CLI for sandboxing AI coding agents), and use Claude Code daily as a practical AI / AI-agent workflow. Passionate about Machine Learning, Generative AI, Game Theory and Quantum Computing.
