What I'm looking for

I seek a role where I can lead performance and automation efforts for scalable FinTech or enterprise systems, integrate CI/CD testing, and drive measurable quality and efficiency improvements.

I am a Senior Performance & Automation QA Engineer with 3.5+ years of experience in high-volume FinTech and enterprise applications, specializing in load, stress, and endurance testing to uncover critical bottlenecks.

I develop and maintain full-stack test automation (API and UI) and integrate tests into CI/CD pipelines using Azure DevOps and Jenkins, achieving measurable gains such as a 15% reduction in API response time and a 40% reduction in manual testing effort per sprint.

I mentor and collaborate across teams to ensure high-quality releases, maintain regulatory compliance for core banking products, and leverage strong programming and database skills (Python, Java, JavaScript, SQL, MongoDB, MySQL, Oracle) to design resilient, scalable test frameworks.
