Noah Bennett

Ex-equity analyst who now models systems instead of stocks

"I was already living in Python and SQL, just calling it financial modeling. The transition to software engineering was more about dropping the Excel dependency than learning to code."

Miles Harrison

Port ops veteran making logistics software that respects real-world chaos

"Port operations taught me that software built by people who have never seen a dock always gets the edge cases wrong. I became an engineer so the edge cases would be handled."

Isaac Morgan

Policy wonk shipping civic-tech tools that actually get adopted

"Government policy work showed me that data transparency can drive real change, but only if someone builds the tools to make it accessible. So I learned to build them."

Priya Nair

Dispatcher turned platform engineer still obsessed with routing problems

"Dispatch is a real-time optimization problem with messy human inputs. Once I framed it that way, the jump to platform engineering felt like a lateral move, not a career change."

Lucas Bennett

Defense intelligence analyst applying threat-modeling skills to appsec

"In intelligence work, you learn to think like an adversary. Application security is the same discipline applied to software instead of geopolitics."
