function first / beauty in precision
Good systems make the difficult feel deliberate.
My work follows the entire chain: design intent, analysis, specification, installation, maintenance, and the decisions made by the people operating the system after turnover.
The focus is mission-critical power, protection strategy, medium-voltage distribution, technical education, and standards language that remains defensible in the field.
02 / professional record
A career built close to the system.
From fabrication and municipal field verification to healthcare design, national-laboratory reliability, and regional application engineering.

06 / a parallel practice
Different room.
Same attention to flow.
Thirteen years behind San Francisco bars informs a second practice: observing service, clarifying stations and handoffs, strengthening training, and making excellent hospitality easier to repeat under pressure.
