Nathan Hayes – Developer Portfolio

About Me

I’m a self-taught developer with over 10 years building web apps, SwiftUI front-ends, and embedded microcontroller systems—connecting hardware and software in real-world comms & IoT projects.

Lately my focus is ham radio infrastructure—repeaters, SDR, digital modes—and tools that make programming and managing radios simpler for everyone.

Outside the lab, I’m a commercial pilot with an instrument rating. The cockpit mindset—checklists, reliability, and clear comms—shows up in how I design systems: predictable, observable, and easy to maintain.

I’m also an avid outdoorsman. Most weekends I’m out with my family—off-roading, building and tuning Jeeps, rock climbing, hunting, fishing, and camping. A lot of my field work blends RF, mapping, and ruggedized gear for real-world use.

Now

Building DispatchLink for live scanner audio + AI metadata.
Expanding LonePeakRadio infrastructure and site links.

How I work

Reliability first (aviation checklists; failover & monitoring).
Don’t break what works—backward-compatible, incremental changes.
Logged & observable—metrics, alerts, and clear diagnostics.
Hands-on—I prototype fast, test in the field, then harden.
