He gets teams in high-stakes industries like automotive and healthcare to close the gap between software development and quality assurance. His goal is to find practical ways to merge coding and testing to ship reliable software. Lately, his work centers on integrating agentic AI into the development lifecycle. He explores how tools like Rovo Dev and Xray can implement features and automate testing safely without dropping the ball on quality. Sergio also teaches programming and software quality at the University of Aveiro in Portugal. ## Past Sessions ### World Congress 2026 Europe - Virtual Stage ยท June 30, 2026 Online - [Improving quality with Agentic AI with Rovo Dev and Xray](https://www.wearedevelopers.com/events/world-congress-2026-europe-virtual-stage/sessions/1557-improving-quality) ## Links - [X](https://x.com/darktelecom) - [LinkedIn](https://www.linkedin.com/in/sergiofreire/)
