Spangler Development — Durham, NC

Building AI apps and health tech

I'm Stephen Spangler, a healthcare worker in Durham who builds software. So far that means a POTS symptom tracker, a study app for the pediatric echo registry exam, a math game my five-year-old tests for me, and AI tools for clients.

About Spangler Development

Spangler Development is a one-person studio in Durham, North Carolina. I formed the LLC in 2026 to publish my own apps and to take on custom AI work for clients.

My day job is in health care, and that's where most of the ideas start. POTS Compass came out of working with POTS patients, and the PE Adaptive Engine is a study tool for the pediatric echo registry, a credential I hold myself. Reef Rescue started as a math game for my five-year-old.
