About me
QA Tech Lead with 10+ years of experience driving testing strategies for global brands such as YBVR, ZINIO, Adidas, and Telefónica. I work across web, mobile, backend, and CI/CD, though my most differentiating focus is automation for XR environments like Android XR and visionOS, combined with AI-driven testing.
I design feedback systems that turn QA reporting into actionable tasks for development teams, ensuring no finding gets lost. I've implemented cross-team collaboration workflows that embed QA into the development cycle from the first sprint, reducing time between detection and fix. On occasion, I've also served as a Scrum Master, helping align teams around quality goals.
Open to collaborations in Castilla y León or remote. Let's talk about optimizing your testing stack.

What colleagues and leaders I've worked with say.
Carlos Díaz Pérez
Frontend passionate / Web dev @ Cakewalk
"I had the opportunity to work with Sergio, who was a QA Automation Engineer overseeing my front-end development. He played a fundamental role implementing a very robust Cypress and Cucumber project. As a professional, Sergio is incredibly dedicated and always willing to collaborate. During my early days at YBVR, he consistently offered his support, making the transition much smoother. On a personal level, he's one of those people you hope to keep in touch with long after professional paths diverge."
Elias Pardo
Quality Engineer
"Sergio is an exceptionally skilled engineer with great experience in automation. If you can imagine it, Sergio can make it happen. During our time together at YBVR, he consistently pushed boundaries, especially when developing a holistic and comprehensive web UI automation solution. Whenever new challenges arose, Sergio was the person I could always count on to tackle them with creativity and enthusiasm."
