Thinking

Thinking in structures.

Define the problem, structure information, assign roles, and verify the result.

Phosynd

From the field.
Into systems.

I began with video and content marketing, then taught myself AI and Python. I now design and operate workflows and products that solve the problems I see in practice.

The persistence I learned in the Marine Corps shapes how I work: when a path is blocked, I find another and finish the job.
