Backend Systems Architect · Engineering Leader
I build the things you don't see —
distributed systems, search engines, payment flows, and whatever lies beyond the horizon.
From hiring to shipping — I build the systems and the teams behind them.
The galaxy below? That's my universe.

The Nuclear Reactor in Your Codebase
Building with AI got us shipping faster than we can read. The codebase is too distributed for any one mind to hold. On what we stopped seeing.
The Moon, Again
NASA flew humans to the Moon for the first time in 53 years. A legacy project revival run in public. What software teams refuse to do, even on camera.
