Sivarubini P.

Are you looking for a Senior/Lead QA Engineer who doesn't just verify that your application works, but actively tries to break it? I'm Sivarubini Pirakas, a Software QA professional with 10+ years of experience in Manual Testing, Automation Testing, API Testing, Database Testing, Mobile Testing, Performance Testing, and Security Testing. I specialize in testing web, mobile, client-server, and enterprise applications and building reliable automation frameworks for critical business workflows. My approach to QA goes beyond happy-path testing. I actively look for edge cases, unexpected behavior, broken workflows, permission issues, invalid inputs, data inconsistencies, integration problems, and regressions that normal testing may miss. MY QA AUTOMATION EXPERTISE • Selenium WebDriver + Java • Playwright + TypeScript • Cypress • Appium for Mobile Automation • Selenium IDE • JUnit • Postman / REST API Testing & Automation • SOAP UI / Web Services Testing • Manual & Functional Testing • Regression & Smoke Testing • Integration & System Testing • Database Testing • Performance, Load & Stress Testing • Security Testing • Cross-browser Testing • Web, Android & iOS Testing WHAT I CAN TEST FOR YOU I can thoroughly test your application from both a QA engineer's perspective and a real user's perspective, including: • Authentication, registration & password workflows • Role-based access control & permissions • Payment & subscription workflows • Messaging & notifications • Forms & validation • API integrations • Database consistency • Web and mobile applications • Multiple tabs & browser sessions • Page refreshes and interrupted workflows • Invalid and unexpected inputs • Boundary and negative test scenarios • Cross-browser compatibility • Regression testing after fixes • Critical end-to-end business workflows I particularly enjoy exploratory testing—trying unusual combinations of actions and inputs to uncover bugs before your customers do. AUTOMATION TESTING I can create and maintain automated test suites using: Selenium + Java | Playwright + TypeScript | Cypress | Appium I focus on creating automation that is: • Stable and maintainable • Easy to understand • Reusable • Suitable for regression testing • Focused on critical business workflows • Easy to integrate into an existing QA process API & DATABASE TESTING I have extensive experience testing APIs and backend functionality using: • Postman • REST APIs • SOAP UI • Web Services • SQL queries • MS SQL Server • MySQL • Oracle I can validate not only the UI response but also the API response, database records, data integrity, and end-to-end workflow. PERFORMANCE & SECURITY TESTING I also have experience with: • Load testing • Stress testing • Performance testing • Bulk testing • Database performance validation • Burp Suite • Acunetix Web Vulnerability Scanner • LoadRunner QA LEADERSHIP EXPERIENCE I have worked as a QA Team Lead, managing and mentoring a team of more than 10 junior QA engineers. My responsibilities included: • Planning QA activities • Creating test plans and test cases • Reviewing test coverage • Assigning and tracking testing tasks • Conducting training sessions • Reviewing defects • Coordinating with developers and project managers • Managing sprint testing and regression cycles • Supporting continuous improvement of QA processes I have hands-on experience with JIRA and Mantis for defect tracking, sprint planning, backlog management, reporting, and QA coordination. MY TESTING PHILOSOPHY Build → Test → Break → Report → Fix → Retest → Automate → Prevent Regression I don't consider a feature "tested" simply because the happy path works. I ask: What happens if the user does something unexpected? What happens if the API fails? What happens if the page is refreshed at the wrong time? What happens if two actions happen simultaneously? Can one user access another user's data? What happens with invalid, missing, duplicate, or boundary-value data? These are the types of scenarios where important production bugs are often discovered. EDUCATION • B.Sc. – Statistics & Financial Mathematics / Computer Science, University of Colombo, Sri Lanka • Bachelor of Information Technology (BIT) • MBA – Metropolitan University, United Kingdom (ongoing) My academic background in Statistics, Computer Science, Financial Mathematics, and Management Science also gives me a strong analytical and problem-solving foundation. WHY HIRE ME? • 10+ years of QA experience • Manual + Automation Testing • Selenium + Java • Playwright + TypeScript • Cypress • Appium • API & Database Testing • Web & Mobile Testing • Performance & Security Testing • QA Team Leadership • Strong analytical and problem-solving skills • Clear bug reporting and documentation • Proactive approach to finding defects • Strong communication and collaboration If you need a QA engineer who will actively search for problems instead of simply checking boxes, I would be happy to help.
