Alex Main, engineer in Mill Valley, CA

I spent twelve years as a corporate lobbyist and earned an MBA along the way, watching technology reshape the world from the policy side. Its pace convinced me not to watch from the sidelines anymore, and I left to study engineering full time and build real things.

Since January 2026, I’ve focused on fundamentals: programming, applied linear algebra, electronics, physics: learned from first principles and tested at the workbench. I use AI to accelerate, not replace, my understanding. Now I’m going deep into robotic reinforcement learning.

After a career spent working with people, they're still at the center of how I think about building. This site documents my journey. I live in Mill Valley, Marin County just north of San Francisco, with my dog, Penny.

Skills

Current Focus: Robot Learning

  • Reinforcement learning: PyTorch, Isaac Lab
  • Simulation: Isaac Sim, Gazebo
  • Robotics middleware: ROS2
  • Now building: Sim-to-Real Self-Balancing Robot

Side Quests

  • KiCad (PCB design), Autodesk Fusion (CAD), 3D Printing, embedded C/C++

What I Learned from 12 Years of Lobbying

  • Negotiation & coalition-building: I've negotiated with legislators, executives, and opposing interests with high stakes on every side.
  • Business & policy judgment: MBA, 2023. I understand what makes technology fundable, regulatable, and deployable, not just buildable.
  • Working through ambiguity: I spent a career making progress when the rules, players, and goals were constantly changing.
  • People first: I explain complex ideas to non-experts and build trust across very different stakeholders.

Foundations (since January 2026)

  • Math & physics: applied linear algebra, circuit analysis, classical mechanics/electromagnetism
  • Electronics: circuit design, bench testing, hardware
  • Programming: Python, C++, Git, Agentic Coding

Education

  • Self-directed engineering study, 2026–present
  • MBA, CSUS, 2023
  • BA, Cal Poly Humboldt, 2013
