About Me

AI Engineer with 3+ years of experience building production-grade LLM systems, data pipelines, and AI-first fintech products. I specialize in the full stack of modern AI infrastructure — from RAG pipelines and MCP orchestration to ERP data ingestion and LLM evaluation frameworks — with deployments on GCP, Azure, and AWS.

Currently building enterprise AI at DataChamps — LLM orchestration, hybrid retrieval, and financial automation.
