Scale operator · COO · Board Director
I build the machine that runs the strategy.
I step in when the ambition is clear but the path isn’t. I find what’s blocking growth, remove it, and build the team and cadence to keep it moving.
My work sits where technology meets the real world: apps that only work when a driver shows up, a bike gets repaired, a shopper finds the item on the shelf. That is where plans meet people, regulation and ambiguity, and where most growth models break.
