  • Technologist | NAND Test & Agentic AI | Pioneering AI-Augmented Engineering Workflows at Sandisk
    Feb 2025 - Present · 1 yr 5 mos

    Pioneered an AI-Augmented Engineering Workflow that transitions traditional, manual testing into a system orchestration model, hands-on deploying product-grade Agentic AI systems to autonomously generate complex viral code and scale stress-testing workloads. Engineered robust multi-agent frameworks that leverage autonomous reasoning, recursive logic, and code self-correction loops, enabling intelligent agents to dynamically translate dense hardware specifications into executable, vulnerability-injecting test programs. Designed and optimized advanced RAG (Retrieval-Augmented Generation) pipelines coupled with high-integrity knowledge base data ingestion systems to parse, vectorize, and extract highly accurate context from complex technical datasheets, schematics, and raw NAND behavior logs. Integrated intelligent agents directly into the core engineering workflow, replacing traditional, linear diagnostics with automated multi-agent failure analysis to radically accelerate root-cause analysis and scale the validation of intricate customer-level failures.
