About

QA Engineer & Incident Analyst working at the intersection of production support, quality assurance, and release validation for a SaaS platform used by business clients. My role focuses on investigating production incidents, reproducing defects, validating fixes, and ensuring system stability before releases. I analyze logs, metrics, and API responses to identify system anomalies, investigate failures, and perform root cause analysis (RCA) to determine why issues occur and how to prevent them. I combine incident investigation with manual QA validation by reproducing bugs in development and staging environments, verifying fixes through functional, integration, and regression testing, and validating REST APIs and system integrations to ensure reliable releases. I collaborate closely with the developer and product owner to clarify requirements, validate product improvements, and support a weekly release cycle through feature validation, regression checks, and final pre-release verification. In addition, I create structured bug reports and technical documentation including test cases, validation checklists, troubleshooting guides, and internal knowledge base materials that help teams resolve incidents faster and reduce recurring issues. My focus is improving SaaS system reliability through production incident analysis, quality validation, and continuous improvement of QA and release processes, including the introduction of basic automated checks for repetitive test scenarios and API validation.
