About Rafael

QA Engineer with 6+ years in software testing and nearly one year in pharmaceutical QA. Strong focus on product quality, testing efficiency, and compliance.

Across the Software Development Lifecycle, I’ve delivered results such as implementing a UI, API, and Data validation regression testing suite that reduced execution time and increased the team´s confidence when changing software. In pharma, I supported production to ensure PPVR: Product Quality, Patient Safety, Validated State, and Regulatory Compliance.

I’m motivated by environments where quality, structure, and continuous improvement create real impact—through automation, diverse testing methods, and cross-functional collaboration.

Seeking QA roles in IT or pharma where I can combine technical testing skills, risk-based thinking, and regulated-industry experience.

I enjoy traveling with my wife, exploring new cultures and cities, and discovering hidden spots along the way. I also like cycling, going to the gym, building LEGO models, and reading, from technical topics to horror stories, which keeps me curious and inspired.
