Stenio Wagner is a senior full-stack software engineer based in Lisbon with 11 years of professional experience and a 5+ year focus on user-facing experiences, event-driven architectures, and scale-to-zero systems. He has driven measurable frontend performance improvements and bundle-size reductions while modernizing UI stacks and migrating JavaScript codebases to TypeScript and stricter linting. Stenio pairs product impact with infrastructure automation—building AI-driven tooling that cut client-analysis time from days to minutes and creating event-based microservices documentation integrated into CI/CD. He’s shipped cross-platform mobile and streaming apps (notably a React Native audio streaming prototype) and champions test-driven development and observability practices that improved conversions and reliability. Colleagues rely on him to translate complex requirements into maintainable architectures that balance speed, scalability, and developer ergonomics.
