What I'm looking for

I’m looking for a QA role where I can own API and performance testing, automate regression with Selenide/Postman, and collaborate in Agile teams to improve quality in always-on fintech and core banking environments.

I’m a Software Quality Assurance Engineer with 4 years of experience handling complete review processes and driving QA from build validation to defect resolution. I specialize in RESTful API testing, data-flow validation across services, and ensuring applications stay reliable in rigorous always-on environments.

I’ve supported critical core banking and fintech systems, including Transact T24 Core Banking System, Symbols Core Banking System, and SOA API testing. I use Postman for functional workflows and validation, and I analyze response times, throughput, and scalability during performance testing.

To improve speed and repeatability, I develop and maintain automated test scripts using Selenide, and I execute regression and functional testing for web applications. For load and performance evaluation, I rely on JMeter to identify bottlenecks and optimize system performance under varying loads.

Working in Agile teams, I document test cases, test results, and defect reports, run sprint-level sanity and smoke testing post-deployment, and collaborate with developers, product managers, and UX designers to catch issues early. I also bring hands-on experience in release management and cross-functional coordination to keep delivery quality consistent.
