Executive overview
Engineer, builder, operator.
I turn ideas into shipped, working products. Over two decades across hardware and software, I've built end to end — founding and scaling a seven-figure consumer brand, engineering live market-intelligence and AI systems, and running independent security research against hardened targets. Concept, sourcing, manufacturing, launch: I take on the whole project, not a slice of it.
