Hire the Best QA Engineers in Amsterdam, NL

Hi! I'm Tannu, a detail-driven QA Engineer with over 5 years of experience in both automation and manual testing for web and mobile applications. I specialize in building scalable testing frameworks using Selenium, Playwright, TestNG and Java, and have a strong grasp on CI/CD pipelines (Azure/AWS DevOps) and tools like JIRA, Postman, and JMeter. 🔧 Whether it's functional testing, UI/UX validation, cross-browser checks, or API and performance testing—I bring deep expertise and a passion for quality. I've helped teams reduce defects by 30%, improved regression test pass rates from 56% to 95%, and boosted test efficiency by 40%. 🚀 I'm also an agile team player who’s led end-to-end testing for multiple user-facing products, mentored junior engineers, and ensured flawless mobile app releases across Android and iOS.

I help teams ship faster and with fewer bugs by building scalable automated tests and detailed QA reports for web, mobile, and desktop apps. Using Playwright, Cypress, and strong API testing, I create regression and E2E test suites that improve product quality, reduce risk, and support long-term growth. I’m a Test Automation Engineer who helps teams ship high-quality products by building strong, scalable, and reliable testing systems. I test web, mobile, and desktop applications manually and through automation, and I focus on catching the issues that slow development down—before they ever reach your users. I work with Playwright, Cypress, API testing tools, regression suites, E2E flows, functional testing, and unit tests. My approach is simple: understand how your product works, break it in every smart way possible, and then build tests that make sure those issues never return. I pay close attention to details that many teams overlook—edge cases, broken UI states, slow API responses, data handling errors, and unexpected user paths. These are usually where the biggest bugs hide. Finding these problems early can save weeks of development time and prevent costly production issues later on. A strong test suite doesn’t just check functionality; it supports your entire development cycle. That’s why I build reusable and scalable automation frameworks that your team can extend even years from now. Whether you continue working with me or bring in another engineer later, the framework will stay clean, organized, and easy to maintain. Clear reporting is another part of my workflow. I deliver structured test reports, detailed bug logs, and evidence-backed findings that help your developers understand exactly what went wrong and how to reproduce it. This improves communication, reduces back-and-forth confusion, and speeds up fixes dramatically. --- ### **How My Work Helps Your Product Grow** * Faster releases through automated regression and E2E coverage * Fewer production issues because bugs are caught early, not after launch * Stronger developer confidence thanks to repeatable, reliable test suites * Clear test reports and bug logs that reduce guesswork and resolve issues quicker * Scalable frameworks your team can reuse as your product grows * Better stability for new features, which supports long-term product expansion * Higher user satisfaction due to fewer broken flows or hidden issues ### **What You Can Expect When Working With Me** * Maintainable automation frameworks built with Playwright or Cypress * Deep exploration testing that uncovers edge cases and hidden failures * Clean, structured bug reports with steps, logs, screenshots, and evidence * API, UI, and functional test coverage designed around real user behavior * A detail-focused approach that strengthens product quality from the ground up If you need someone who can think like both a tester and a developer, spot issues early, build automation that lasts, and communicate clearly through detailed reports, I’m here to help you create a stronger, safer, and more scalable product.
