01 / The operating system
Technical depth is useful. Leverage is the point.
I work across the full delivery loop: translating business needs into system boundaries, making technology choices, shaping teams, and getting reliable software into production.
My best work sits where architecture, quality, and people meet. The result is less heroics, clearer ownership, and products that can keep moving after launch.
