About Lok S.

I’m a passionate QA Automation Engineer (SDET) with over 8 years of hands-on experience ensuring software quality across insurance, finance, healthcare, and e-commerce industries. My goal is simple to help teams deliver reliable, high-performing software faster and with greater confidence through smart, scalable automation. I specialize in UI, API, and mobile automation, building maintainable frameworks using Selenium WebDriver, Playwright, Cypress, Appium, TestNG, JUnit, and Cucumber. With deep experience in API testing through Postman, RestAssured, GraphQL, and SoapUI, I’ve validated complex integrations and backend data flows that power enterprise systems. My expertise extends into DevOps and CI/CD, where I’ve embedded automated testing into pipelines using Azure DevOps, Jenkins, GitHub Actions, Octopus Deploy, Docker, and Kubernetes. This integration has reduced manual work, increased release frequency, and improved deployment stability. I’m also comfortable working in cloud and containerized environments and experienced with databases such as SQL Server, Oracle, MySQL, and MongoDB. Beyond functional automation, I bring solid experience in performance and load testing using JMeter and LoadRunner, as well as advanced reporting with Allure, Extent Reports, and Tableau. These insights provide teams with real-time visibility into testing progress, risk, and product readiness. I thrive in Agile and Scrum environments, collaborating with developers, analysts, and product owners to integrate testing early in the SDLC. I’m skilled in test management tools like Jira, TestRail, and HP ALM, ensuring seamless defect tracking and sprint planning. Throughout my career, I’ve: Built Page Object Model (POM) based frameworks to improve test scalability and reusability. Reduced regression cycles by 50% through parallel execution and Selenium Grid setups. Automated OCR validations for financial data accuracy. Designed self-healing test frameworks that adapt to UI and API changes. Delivered faster, more stable releases by aligning automation with CI/CD. I’m currently exploring AI-driven automation, cloud testing, and performance optimization, always focused on improving quality, speed, and efficiency. If you’re looking for a QA Automation Engineer who can drive automation strategy, streamline testing workflows, and strengthen release confidence, I’d love to connect and contribute to your team’s success.

   At GAINSCO, I focus on automation for Guidewire Claim Center and Duck Creek PAS in the auto insurance domain. I built backend automation to validate policies and claims, which improved accuracy and reduced manual effort. Using Selenium with JUnit, I developed a scalable automation framework that cut regression cycle times by 40%. I also delivered faster API integration checks using Rest Assured and strengthened release reliability by integrating automation into Azure DevOps pipelines while generating detailed Allure reports.
