I design and execute manual tests for exploratory, usability, and edge-case scenarios to uncover critical defects and strengthen product reliability.

I build and maintain scalable automation frameworks using tools such as Selenium, Playwright, TestNG, and pytest, continuously enhancing automation coverage, stability, and execution efficiency across key workflows.

In addition, I mentor junior QA engineers and advocate for best practices in quality engineering to elevate team performance.

I also automated the end-to-end ETL pipeline testing workflow, reducing manual testing effort by six hours per week and improving pipeline stability by 65%, while developing APIs to generate Salesforce source data, manage authentication flows, and validate backend data for comprehensive ETL testing.

I collaborated closely with business analysts and product stakeholders to translate requirements into structured test plans and quality standards. My work included automating front-end regression tests using Selenium and TestNG, building comprehensive regression suites, and implementing post-production smoke testing, which contributed to a 70% reduction in critical bugs and improved release stability.

I also introduced structured release and defect management practices, including code freezes and improved bug tracking in Jira. In addition, I developed and maintained an automation framework with Selenium WebDriver, configured Jenkins pipelines for automated regression runs, and performed performance testing using JMeter and Siege to identify system bottlenecks.

My role further involved automating API validation with REST Assured, migrating automation to Node.js using Headless Chrome and Puppeteer to improve execution efficiency, and leveraging Vertica and MySQL queries to validate backend data and support reliable test automation workflows.

I actively participated in Agile ceremonies, collaborating with cross-functional teams to align testing efforts with sprint objectives and improve visibility into potential quality risks.

My responsibilities included performing GUI, functional, and regression testing to verify system stability and maintain a consistent user experience. I also maintained and enhanced automation scripts after each release cycle, expanding regression coverage and improving validation efficiency.

In addition, I identified high-risk regression scenarios and automated key test cases using Selenium, and successfully uncovered three critical defects in a UI-targeting feature before release, helping prevent potential production issues and strengthening overall release reliability.
