Senior Software Engineer / Full-stack
Building precise, scalable web experiences. Six years engineering production systems for finance, media and identity at Brazilian scale.
Engineering as a craft, not a checkbox.
I'm Windsor — a senior software engineer with six-plus years shipping web platforms that millions of people rely on. I work end-to-end across the stack, from low-latency Go services to type-safe React frontends, and I care about the boring, important things: observability, accessibility, and code that the next engineer can read in a single sitting.
My approach is methodical. I treat every system like a lab experiment — measurable, reproducible, isolated where it matters. The goal isn't novelty for its own sake; it's quietly excellent software that holds up under load.
