Binderiya Chinbaatar

I’m a QA Engineer with 3+ years of experience in manual and automation testing, specializing in API and backend testing. I focus on defect prevention, test optimization, and measurable product quality improvement.

At Zero Technology, I performed end-to-end testing of mobile applications (Android, iOS) with Appium, helping ensure successful product launches with zero critical production defects. I designed and executed 120+ test cases to achieve 95% functional coverage and detected 110+ defects before release.

I’ve automated API test cases using Playwright (primary) and Katalon, reducing regression testing time by 70%. I also validated POS integrations, ensuring 100% transaction flow accuracy.

Previously at Trade and Development Bank, I led QA activities during Jira implementation to improve defect tracking workflows. I automated repetitive testing tasks using JMeter and Power Automate, cutting manual effort by 30%, and I collaborated closely with cross-functional teams during deployments.
