What I'm looking for

I’m looking for full-time remote or long-term contract roles where I can own QA end-to-end in Agile teams—leading STLC, REST API and data validation, and growing into Playwright test automation with CI/CD.

I’m a results-driven Senior QA Engineer with 6+ years of enterprise software testing experience across Microsoft Dynamics 365 CRM/ERP, Salesforce, banking, and telecommunications. I’ve supported global clients with direct US client engagement in an EST-aligned remote capacity, thriving in distributed, async team environments.

I reduce risk through full-cycle STLC execution—test planning, risk-based test strategy, execution, defect triage, UAT facilitation, and sign-off—using Azure DevOps Test Plans, Jira, and Zephyr. I’ve led REST API testing across 15+ microservices, improved outcomes by reducing defect leakage by 30%, and achieved 99.9% data integrity through SQL-based validation and data reconciliation.

I’m particularly proud of delivering quality beyond “pass/fail,” including WCAG 2.1 accessibility testing and building 300+ test cases with strong requirements-to-test traceability. Currently, I’m expanding into test automation engineering with Playwright (JavaScript/TypeScript) and CI/CD pipelines via GitHub Actions, while mentoring junior QA engineers to raise team delivery velocity.
