The Evolution: Mechanic to Controller to Engineer

Phase 1:

Distributed Systems

Automotive Master Tech

  • Complex Electrical Diagnostics
  • CAN/LIN/Fiber Bus Logic
  • "Black Box" System Analysis

Phase 2:

Human Systems

Air Traffic Controller

  • Real-time Decision Making
  • Absolute Reliability
  • Algorithmic Routing
  • Previously Held Secret Clearance (Navy/FAA)

Phase 3:

Digital Systems

Infrastructure Engineer

  • Scalable Architecture
  • Linux Networking & IoT
  • Architecting the "Glue"
"I am no longer just operating or fixing these systems; I am architecting and programming the glue that holds them together."

Objective

To bring this deep operational empathy and troubleshooting rigor to a professional Software Engineering role. I don't just write code; I build tools that work in the real world.
