Noah Hellyer

Full-Stack Developer

I build where technology meets misunderstanding.

I try to eliminate that disconnect, figure out what people need, and redesign until that gap disappears.

I build for the web — heavy on Next.js and AWS — and the part I care about most is where software stops making sense to the person using it. Comfortable from the interface down to the infrastructure, on systems that hold up under real users.

Denver Percussion logo

Denver Percussion

Lead Developer · sole engineer on all internal software

Built three internal applications end to end, removing an estimated 1,000+ hours of manual work and cutting product creation from 30+ minutes to under 10 — unified search across two inventory systems, AI-assisted product generation, and photo capture handed to a phone by QR code. Parts Maker, a Next.js app on Vercel, runs against live production data through MusicShop 360, the company POS, e-commerce, and payments platform; the services behind it are containerized on AWS ECS over EC2.

Leadership

Cherry Creek Computer Science Club

  • Co-President 2026–27
  • Vice President 2025–26
  • Linux Chair 2024–26

Helped launch CreekCTF and ran it two years running — 12+ teams across two schools each year — owning every piece of the competition infrastructure: CTFd on AWS, the event site, and many of the challenges. Taught Linux to complete beginners and built the club sites for a 60+ member club.
