about me

i’m a software engineer interested in systems.

i spend a lot of time thinking about distributed systems, simplicity, abstractions, and the fundamentals behind good engineering. i enjoy working close to the core of a system. behavior, complexity, trade-offs, and decisions over time.

i write about engineering, computer science, systems, technology, work, and thoughts on the industry.
