End-to-End Test Strategy & Device Launches: Led release readiness, test planning, and Go/No-Go quality sign-offs for flagship devices (Echo Show 15 - 2nd Gen, Echo Show 21, FireTV Omni QLED series), ensuring multi-regional release execution across US and EU markets with zero critical post-launch defects.

Platform & OS Stability Engineering (Vega OS): Contributed to the new Vega OS platform launch by designing and executing stability and performance test strategies, identifying 15+ critical blocker defects early, and improving overall OS stability by 30%.

GenAI / LLM Workflow Validation (Alexa+): Validated LLM-driven workflows and conversational feature readiness for the integration of generative AI (Alexa+) into communication domains across existing Echo devices.

Defect Backlog Reduction & RCA: Managed end-to-end release readiness for 9+ major device software rollouts; drove regression testing and defect fix prioritization, reducing open defect backlogs by 95% and establishing SOPs for defect leak root cause analysis (RCA).

Quality Audits & Operational Efficiency: Conducted internal quality audits to raise team release standards, implemented standardized device sign-off matrices in Jira, and reduced team operational efforts by 20–35%.

Team Leadership & Capacity Management: Acted as primary point of contact for task planning, bandwidth allocation, and ETA estimation for a 10–12 member QA team; mentored new hires to maintain execution quality and sign-off velocity.
