Experience
SanDisk (via Magnit) Bengaluru, India
Design Verification Engineer | ML, Generative AI & Computer Vision Jul 2024 – Mar 2026
- Architected an NLP/ML text classification system for error log processing, reports, and test specs via SpaCy, NLTK, and fine-tuned models (Hugging Face, PyTorch); cut manual triage by 60% and earned the Trade Secret Award (2025).
- Engineered a RAG-powered debug assistant using LLMs (Llama, Mistral) and LangChain, enabling engineers to query past failure reports, test cases, and internal wikis in natural language to surface root causes; reduced product launch timelines by 15%;
deployed via Azure ML and MLflow with CI/CD.
- Built an end-to-end wafer defect detection system for NAND flash inspection using PatchCore (unsupervised anomaly detection)
and fine-tuned EfficientNetB0 (supervised classification), with Grad-CAM for defect localization; deployed as a FastAPI + Docker service on Hugging Face Spaces, achieving 94%+ AUROC on the MVTec industrial anomaly benchmark and reducing manual inspection effort by∼60%.
