About
Performance is a product feature.
I work across backend systems, desktop tooling, and developer platforms with an emphasis on throughput, fault tolerance, and implementation clarity. My projects tend to start where abstractions get expensive: console rendering, storage, validation, build-time tooling, and the systems around them.
The throughline is consistent: remove waste, keep the API honest, and build software that stays dependable under pressure.
Experience
Operational depth across product, support, and systems work.
