What I'm looking for

I’m looking for a QA/automation role where I can own end-to-end testing (especially API) and improve defect detection and reporting. I want a team that values Agile execution, fast learning, and measurable reliability gains.

I’m a results-driven Quality Assurance Engineer with 3+ years of experience in automation testing, API validation, and Agile development environments. I bring backend development know-how to improve bug tracing and deliver precise, actionable reporting to development teams. I focus on building test strategies that prevent production defects across web, mobile, and API platforms.

In my current role, I develop and execute 100+ regression test cases with Katalon Studio for web and back-office systems, speeding up test documentation through AI-assisted workflows. I validate critical financial accuracy by cross-checking frontend values against core banking records, trace API-level defects through gateway log analysis, and support loan onboarding and document legalization verification. I also lead structured defect reporting and consistently validate end-to-end KYC flows, including edge cases in user input validation.

Previously at AMAR BANK, I strengthened reliability in installment and disbursement flows using edge-case testing and persistent E2E verification. I collaborated with QA leadership to build automated journey flow coverage with CodeceptJS, reducing manual testing from hours to about 10 minutes, and improved backend confidence with Karate framework and MongoDB validation. Across projects at PRIVYID, I architected API and E2E automation strategies with Jest/Postman and Cypress integrated with GitLab CI/CD, achieving major reductions in defect leakage and regression effort.
