Full-Stack Engineer & Security

Building systems. Breaking barriers.

I build production-grade software and find vulnerabilities in real-world systems. From high-traffic game servers to Linux security tooling I ship things that work at scale.

Currently pursuing a Master's in Computer Engineering, with a foundation in Computer Programming and Information Systems.
