What I'm looking for

I seek engineering roles focused on systems, compilers, or cybersecurity where I can solve low-level problems, optimize performance, and grow in a security-minded, collaborative team.

I am a Computer Science student with hands-on experience in systems programming, compiler construction, networking, and applied cybersecurity; I build performant, cross-platform software and design exploit/defense tools backed by rigorous testing and measurable performance gains.

I have led customer-service teams, managed web presence for small businesses, and contributed as a teaching assistant; I combine practical industry-facing experience with strong academic projects that demonstrate optimization, reliability, and security-first engineering.
