Agentic AI for
silicon engineering.

Senior AI Engineer at Cisco Silicon One, building agentic LLM and RAG systems for PD, DFT, and MBIST. My work spans LLM fine-tuning, AI infrastructure, AIOps, and production operations. I bring 8+ years across software, data, and AI engineering, including earlier e-commerce systems serving 24,000+ SKUs and analytics pipelines processing 1M+ records.
