01. About me

I'm a software developer with a passion for systems programming and understanding how everything works beneath the surface. Currently sharpening my craft at 42 School, a peer-to-peer, project-based engineering programme with no lectures, no shortcuts, only code.

Passionate about low-level coding, automation, and building systems that are not only functional but secure by design. I love understanding how things work beneath the surface.

After years of professional experience in management roles within tech services outsourcing companies, I'm now making the transition into the tech industry full-time, bringing a strong foundation in people, processes, and the business side of technology.

Outside of code: cat person, longtime gamer, Souls games, Baldur's Gate, Path of Exile, survival games, and a Magic: The Gathering player since a young age.
