Advanced Micro Devices (AMD)

• >Architected an end-to-end agentic AI triage system in Python that automatically discovers, ranks, and drafts GPU driver bug tickets from online user feedback, showcased to leadership and now being adopted org-wide.
• >Scaled issue triage to 10,000+ community posts per run by engineering a Python pipeline that combined semantic embeddings, LLM classification, and clustering to surface high-priority GPU issues.
• >Built a dual-pipeline Python architecture that reused shared collectors, LLM clients, and PostgreSQL/Redis infrastructure across both a triage workflow and MCP tool, eliminating duplicated retrieval and triage logic.
• >Orchestrated full-cycle Jira ticket drafting through an LLM agent chain that calls internal bug-tracking and crash-analysis APIs over MCP, with schema-validated outputs and source-linked evidence.

Advanced Micro Devices (AMD)

• >Shipped a real-time AI reporting tool in React, Python, and FastAPI that captured live spoken feedback during GPU test runs, replacing manual note-taking with LLM-refined reports.
• >Engineered a low-latency speech-to-text pipeline with Whisper, Silero VAD, and PyTorch, tuning custom audio preprocessing and internal terminology biasing to achieve 93% accuracy on GPU-specific vocabulary.
• >Enhanced internal full-stack platforms built with React, Node.js, Express.js, Redux, and Snowflake, and shipped features for scheduling, real-time monitoring, and reporting across distributed GPU test plans.

Ford Motor Company

• >Developed Python validation pipelines and reusable test harnesses for over-the-air firmware updates across Wi-Fi and cellular conditions, supporting release readiness and 99.9% update reliability across 5 connected-vehicle models.
• >Implemented CI and pre-release regression workflows by building a Python test-prioritization scheduler that ranked cases by historical failure rates, improving triage speed and reproducibility and saving 10+ developer hours per week.
• >Improved in-vehicle wireless stability by 15% by authoring Python regression suites for Wi-Fi hotspot and emergency-call features, root-causing handoff latency from multi-gigabyte packet captures.
