I’m a Linux enthusiast, systems engineer, and occasional open source contributor, also a cloud native advocate at heart. I care more about why something breaks than just fixing it, which is probably why I ended up in infrastructure and cybersecurity. I’ve spent years across cloud platforms, incident response, and system administration, and somehow still get excited about a well designed architecture diagram. In my free time, I’m still writing code, because I enjoy having custom tools tailored specifically to me, or just because I want to know deep down how a protocol works, or because there’s a problem at work that isn’t solved yet and needs some kind of automation.
