About

I’m a backend focused engineer building scalable systems and diving into DevOps. With a long-standing background in cybersecurity, I enjoy understanding how systems break just as much as how they’re built. Currently exploring AI/ML out of genuine curiosity and passion. I love breaking, building and engineering products that create real impact in the technology space.
