I wrote my first line of production code in Brazil more than two decades ago. Since then I have been a developer, a consultant, and for the last eight years the person teams call when their test suite is flaky, slow, or missing entirely. These days I spend most of that instinct on AI agents and automation instead, catching what an agent gets wrong before it ships, not just what a human gets wrong.
I am based in Canada, work in English and Portuguese, and I am at my best in the gap between building fast and building something that still works in a year: real testing, real reliability, not a demo that happens to work once.
Outside of work I write psychological thrillers under a pen name. It turns out that hunting plot holes and hunting bugs are the same skill, and I cannot switch either one off.
