Versatile Computer Engineer & QA Specialist based in Mozambique. I bridge the gap between development and quality assurance with expertise in Automation, Cybersecurity, and Full-Stack Engineering.

About Me

Bridging technical innovation with rigorous quality standards.

I am a Computer Engineer with a strong foundation in software testing and technical support. My journey has taken me from Warsaw to Mozambique, working with global leaders like Infosys and Teleperformance. I specialize in Agile Testing Methodologies (ISTQB Certified), cybersecurity, and backend development. I don't just find bugs; I analyze root causes and collaborate with developers to build resilient systems.
