Selected Public Work
Deployed automation platform that best represents product breadth across backend, web administration,
realtime tooling, support flows, and connected-device runtime behavior.
- ASP.NET Core backend with JWT auth, Blazor web surface, SQL-backed state, SignalR updates, and MQTT-oriented device flows
- Strongest public sample for reviewing auth, persistence, realtime communication, and product runtime orchestration
