FOUNDER / SENTINEL TECH SYSTEMS LLCAndrew KnudsenFounder — Sentinel Tech Systems LLC
Andrew Knudsen founded Sentinel Tech Systems with a focus on building software shaped by practical experience.
His background in law enforcement helped drive development of Helios, a public safety software project focused on operational workflows and records management.
The company's work has since expanded to Herigen, a reptile management and genetics beta, and Hestyn, an early healthcare AI research initiative.
A company built
around solving problems.
Sentinel's development work began with public safety tools influenced by firsthand operational experience. The same approach to focused software engineering now supports projects for reptile keepers and breeders.
Hestyn is a newer research initiative exploring healthcare developer environments. Each product retains its own identity while remaining part of Sentinel Tech Systems LLC.
