What I'm looking for

I am seeking a QA role in a collaborative, security-conscious team where I can apply DevOps and cybersecurity experience to strengthen testing, automation, and operational excellence.

I am an Information Systems graduate with a strong technical background in infrastructure, DevOps and cybersecurity, transitioning into Quality Assurance to apply my preventive risk mindset and operational rigor.

Across roles in cybersecurity and cloud DevOps I implemented automation with Ansible, Git and Terraform, managed AWS and Linux environments, and applied standards like ISO 27001/27002/22301 and NIST to improve security posture.

Proactive and analytical, I combine manual and automated testing experience (Selenium, Cypress, Postman, JMeter) with a commitment to continuous improvement, seeking to join a QA team to raise operational excellence and security.
