Approach
“Train Hard.
Think Deep.
Live Clean.”
I build tools from the inside out. Every application starts with lived domain experience β not a brief. After 32 drug-free years in bodybuilding and a decade leading global marketing teams, I understand what fitness clients, coaches, and operators actually need from software.
My integration of AI is intentional and principled. I use Claude as a reasoning layer β not a shortcut. Whether that’s generating brand-voice content at scale, interpreting market signals, or acting as a decision engine inside a trading plugin, the AI is doing real cognitive work within a system I’ve architected to be safe, testable, and explainable.
I’m drawn to roles where domain depth matters as much as technical depth β where the person building the tool is also the person who would use it.
