Hire the Best Test Automation Engineers

Senior QA Engineer with 13+ years of experience across manual testing, test automation, performance testing, and QA leadership. I specialize in building QA processes and automation frameworks from the ground up. I've done this repeatedly, for companies ranging from Web3 startups to fintech platforms to SaaS products, often as the sole QA resource with no existing process to build on. What I bring to a project: 🤖 TEST AUTOMATION I design and build automation suites tailored to the platform: Synpress/Cypress for Web3 wallet flows (~300 automated tests), Appium/WebdriverIO for mobile, and Selenium/Protractor for traditional web apps. At one company, I helped grow a suite to ~2,000 automated test cases across 8-10 products and cut regression testing time by over 90%. 🛠️ QA PROCESS & LEADERSHIP I've built QA operations from scratch multiple times: bug triage workflows, JIRA structures, release gates, and regression checklists. I've also led teams of up to 18 QA engineers and trained manual testers to write and maintain their own automated tests. ✅ FULL-STACK TESTING COVERAGE Functional, regression, UAT, performance/load (JMeter), API testing (Postman/Newman), and post-production monitoring. I'm comfortable owning quality end-to-end, not just executing test cases. 📊 BUSINESS ANALYSIS I've regularly doubled as a BA, writing acceptance criteria, Gherkin specs, and bridging the gap between stakeholders and engineering. I work well as an independent, self-directed QA resource. I don't need heavy oversight to figure out what a product needs and build the right quality process around it. ISTQB-certified. Experienced working remotely with US and international clients. Let's talk about what your product needs and how I can help you ship with confidence.

🚀 8,000+ automated test cases. That's what I built for a live fintech bill-payment platform at TPS Worldwide. But before a single line of automation code was written, every test scenario was planned, documented, and validated manually first. That's how good automation gets built. 6 years across Fintech, Core Banking, Digital Health, and E-Commerce — doing both sides of QA properly, and genuinely enjoying every bit of it. On the manual side, I handle test planning, requirements analysis, exploratory testing, regression cycles, UAT coordination, and structured bug reporting in Jira and TestRail. I've run full QA audits on web applications, documented 15 critical bugs in a single audit cycle, and led Visa Direct integration testing at Meezan Bank in direct collaboration with Visa and Avanza teams. Precision, communication, and domain knowledge — not just a checklist. ✅ On the automation side, my stack covers Playwright and Cypress for web, Selenium and SpecFlow BDD for enterprise, Postman and REST Assured for APIs, and GitHub Actions or Azure DevOps for CI/CD. I've reduced deployment errors by 30% through pipeline-integrated test suites and improved API coverage by 40% on a multi-product SaaS platform. I've migrated entire frameworks from Cypress to Playwright when project requirements shifted — that flexibility matters on long-running engagements. ⚙️ I write in JavaScript, TypeScript, and C#. I've trained internal QA teams on automation practices and love working alongside existing teams, not just independently. ✨ What I test and deliver: 🔍 Functional and Exploratory Testing Smoke, sanity, regression, and exploratory testing across web and mobile. Every bug report includes reproduction steps, screenshots or video recordings, severity ratings, and developer-ready notes in Google Sheets or your preferred format. No guesswork, no vague reports. 🤖 Automation Testing UI and API automation in Python, JavaScript, and TypeScript. Frameworks built to last, not just to pass the current sprint. If it can be automated, we automate it right. ⚡ API and Performance Testing REST API validation with Postman and REST Assured. Load and stress testing with JMeter and k6 to confirm your system holds up under real traffic conditions — before your users find out it doesn't. 🎨 UI/UX and Usability Testing I flag confusing flows, broken interactions, and design inconsistencies that users will notice before your developers do. You get practical improvement suggestions alongside the bug list, not just a defect count. 📱 Cross-Browser and Device Testing Chrome, Edge, Firefox, Safari, and mobile browsers. Tested on real physical devices: 📱 Android Phone: Samsung Galaxy A07 (Android 16) 📟 Android Tablet: Samsung Galaxy Tab A9+ (Android 14) 🍎 iPhone 14 Pro (iOS 26.4.2) and iPhone 16 Pro (iOS 26.3.1) 🍎 iPad: No physical device, but covered via LambdaTest and BrowserStack on real cloud hardware — real devices, not simulators. Every bug report includes the exact device model, OS version, and browser where the issue was found. 📋 🏆 Certifications ICT Quality Assurance Engineer — Australian Computer Society (ACS) ICT Support and Test Engineers — ACS Software Tester — ACS ⏰ Available immediately, 6 hours/day. Whether you need disciplined manual QA, a production-grade automation framework, or both — let's talk about what your project actually needs. I'd love to help you ship with confidence! 🙌

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.

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.
