What I'm looking for

I seek QA roles where I can drive high-quality releases in Agile teams, expand API and test automation skills, and contribute to clear defect resolution processes.

I am an experienced QA professional with over five years focused on manual testing for enterprise platforms and test reporting tools, skilled in functional, UAT and regression testing. I apply rigorous test case design, defect lifecycle management in JIRA, and a SWAT approach to prioritize critical scenarios and align results with acceptance criteria.

I have supported Agile teams by executing TOSCA test cases, performed basic API verification using Postman and Swagger, and coordinated QA efforts across e-commerce and enterprise projects to ensure high system stability and successful releases.
