Luca Ahumada
Quality Enablement Engineer
Summary
Quality Enablement Engineer with 8+ years building the test platforms, CI/CD quality gates, and observability practices that let engineering teams ship quickly and safely. I focus on making quality the path of least resistance — reducing flaky tests, shortening feedback loops, and embedding testing literacy across teams rather than acting as a gatekeeper.
