Deep.
Six years at NASA writing software for Mission Control. Software engineer to principal engineer leading the team. Code that flight controllers ran live, with astronauts on the other end.
Joined Epsilon3 as principal engineer to build the prototype. The prototype became the heart of the product, and the product became the #1 procedures platform in the world — software for rockets reaching orbit, landers headed to the Moon, satellites overhead, and the factory floors that build them.
Five years from prototype to Head of Engineering. 15 engineers, four squads. The work: design the org, hire senior engineers, set technical direction, sell to customers, present to investors, partner with product and design. FedRAMP, live-database migrations, new modules — all shipped along the way.
Apprenticed at Mission Control.
Software engineer to principal engineer leading the team. I mentored, owned architecture, and worked directly with flight controllers — building the systems that ran the missions: telemetry, command, anomaly tooling. Code that had to work the first time, because the people on the other end were astronauts.
