What I'm looking for

I’m looking for a team where I can drive QA quality end-to-end—manual and automated API testing, strong cross-platform validation, and data-informed incident resolution—while working in an Agile/Scrum culture that values clear documentation and continuous improvement.

I’m a Systems Engineer with 6+ years of experience in software quality assurance, covering functional, regression, and API testing across web, backend, and mobile environments. I lead quality from execution through validation, using tools like Postman and Cypress for dependable manual and automated testing, plus Jira and Confluence to keep defects and documentation clear and actionable.

I’ve also built real operational impact by leading the Wompi payment integration—validating communication between financial systems and the payment gateway to enable immediate payment registration and eliminate manual reporting. In my day-to-day work, I combine testing with data analysis by running SQL (PostgreSQL) to investigate incidents, identify root causes, and support continuous improvement in Agile (Scrum) teams.
