Noah Hellyer

Full-Stack Developer & Cybersecurity Practitioner

I build the systems people learn to break.

I build for the web — heavy on Next.js and AWS — and stay active in cybersecurity through CTFs and student club leadership. Comfortable from frontend down to the network layer; I like systems that hold up under real users and adversarial poking.
