• Conduct test case reviews against certification checklists and standards.
• Prepared verification documentation, test reports, and certification evidence.
• Collaborated with system, development, and certification teams to resolve requirement discrepancies and defects.
• Supported regression testing and impact analysis during software updates.
• Perform review on different test files such as test spreadsheet, traceability, test harness and test manager.
• Creating functional and non-functional bugs and reporting issues found during compliance review.
• Test execution in PIL and MIL modes along with different compliance checks.
• Result analysis for MCDC, statement and decision coverage.
• Created branch and pull requests in Azure DevOps to facilitate review comments and configure review checklist for improved compliance tracking.

Project 2:

Client: Rolls-Royce | Tools: CUTE, PTC Integrity.

• Performed High-Level Requirement Testing (HLRT) and Low-Level Testing (LLT) for safety-critical engine control and monitoring software in compliance with DO-178B/C Level A standards.
• Conducted structural coverage analysis including MC/DC, Decision, and Statement coverage to achieve Level A certification objectives.
• Generated and executed component-level test harness (.ath) files using CUTE.
