About me
I'm a DevOps Engineer at Anamata where I work on infrastructure automation and Pega development. At 2 meters tall, I have a good overview of both server racks and code architecture.
I spend most of my time writing Python and Rust, setting up CI/CD pipelines, and making sure systems don't break at 3 AM. I genuinely enjoy the challenge of building reliable infrastructure and creating tools that make mine and other developers' lives easier.
In my free time, I work on personal projects like an encrypted chat TUI in Rust and contribute to open source when I can. I'm also a big Formula 1 fan - there's something satisfying about both well-tuned race cars and well-optimized code.
