Message

At TDW Group, I build production AI features with Amazon Bedrock, including custom agents, RAG over Bedrock Knowledge Bases, and multimodal tool-calling. I add reliability through grounding policies, output validation against inventory, and read-only execution boundaries.

I also own a multi-tenant GenAI assistant platform on AWS, with isolated stacks for enterprise clients and warm-standby failover. Previously, I built agent tools connecting Bedrock to PostgreSQL and Power BI, and developed TypeScript applications across React, Next.js, and Angular.
