AI Field Engineer at Credit Union of Texas, deploying Gemini multi-agent workflows and production RAG for financial services.

United States

Message

At Credit Union of Texas, I integrate Google Gemini through Vertex AI and build multi-agent workflows with Google ADK, LangGraph, and LangChain for financial services applications.

I built production RAG and GraphRAG pipelines for financial document intelligence, connecting semantic search with grounded responses. I also implemented PII detection and masking, DLP controls, and guardrails for regulated data.

At Veterans Affairs Department, I developed LangChain RAG applications for enterprise knowledge management and Python services for AI workloads on AWS. I also worked on NLP document processing and production monitoring for federal systems.

Earlier at Radixweb, I built NLP and retrieval pipelines, model evaluation frameworks, and Python data workflows. My work spans open- and closed-model LLMs, evaluation, deployment, and AI governance.
