Engineering clarity intocomplex systems.
Follow the professional storyView LinkedIn profile↗I work at the intersection of power-systems engineering, data, technical communication, and product thinking.
The through-line is simple: give people a clear model, direct feedback, and room to think. Across my side projects, that means turning specialist knowledge into approachable tools people can learn from, test, and share.
