I'm a QA Engineer with 4 years of professional experience delivering end-to-end quality assurance for large-scale consumer applications — both manual and automated. I specialize in cross-platform testing across Android, iOS, mobile web, and desktop web. For automation, I work with Playwright (web) and Maestro Studio (mobile), and I have prior experience with Selenium and Appium. I use Postman for API testing and validation. What sets me apart: beyond UI and functional testing, I also perform data tracking validation — verifying that user-triggered events are correctly captured in analytics tools like BigQuery and Amplitude. This is a layer of quality most QA engineers don't cover. My experience includes leading test planning and strategy, writing and executing test cases, maintaining live automation suites, and collaborating directly with developers and product managers throughout the full development cycle. I've applied these skills at Traveloka, one of Southeast Asia's largest online travel platforms, where I own quality for features used by millions of users. Whether you need a complete QA setup from scratch or ongoing testing support, I bring a full-ownership mindset to every project.
