What I'm looking for

I am looking for a QA/Automation role in FinTech where I can lead test automation efforts, improve regression stability, integrate tests into CI/CD, and collaborate on release quality and faster delivery.

I am a Full-Stack QA Engineer with 4+ years ensuring end-to-end quality in complex FinTech systems, including banking, payments, and crypto. I combine deep manual QA expertise with practical automation—using Codeception (PHP), Selenium, SQL, Jenkins and BDD—to improve data accuracy, regression stability, and release velocity.

I built ~1600 automated API tests to reach full API coverage, developed scalable UI/API suites that reduced manual regression and sped releases, and integrated tests into CI/CD pipelines. I focus on scalable, maintainable automation (expanding in Java and Playwright), clear QA reporting, and collaborative release coordination to minimize production defects.
