ABOUT / SIGNAL, NOT NOISE

A backend engineer who sees the whole product.

I move comfortably from architecture and API contracts to deployments, observability and the user-facing consequences of technical decisions. Recently, I also led the adoption of AI-assisted code review, risk analysis and engineering workflows.
