Designed and executed 200+ requirement-based test cases for railway signaling modules (CBTC, TCAS, ASFA), achieving ~95% test coverage across functional and regression cycles. Detected and documented 50+ critical defects during system and smoke testing phases, preventing issues from reaching production and reducing post-release bug rate by an estimated 30%. Tracked and resolved defects end-to-end using Mantis Bug Tracker, maintaining average closure time under 3 business days across all severity levels. Validated real-time train–track communication data and UI behavior against business requirements, ensuring zero critical data-accuracy failures across 4 consecutive release cycles. Collaborated with cross-functional development teams on root cause analysis, reducing recurring defects by improving test data quality and environment setup standards. Contributed to ISA (Independent Safety Assessment) audit preparation, supporting compliance verification against CENELEC EN 50128 / EN 50129 safety standards. Supported requirement analysis and test planning sessions, improving overall test coverage by 20% through systematic scenario identification for edge cases in train movement logic.
