Senior Full Stack AI Engineer at ConsultingIQ who delivered AI SaaS platforms and RAG pipelines that improved retrieval accuracy by 30%.

Message

At ConsultingIQ, I led the architecture and end-to-end development of AI-powered SaaS platforms for customer support, document intelligence, and workflow automation.

I implemented RAG pipelines with LangChain, LangGraph, OpenAI GPT-4, Anthropic Claude, Pinecone, and pgvector, improving contextual retrieval accuracy by approximately 30% across large document collections. I also developed AI agents for multi-step reasoning, tool calling, and automated business workflows.

At Austin Artificial Intelligence, Inc., I developed production AI applications and conversational systems for enterprise customers. I built RAG architectures using Pinecone, FAISS, ChromaDB, and pgvector, and optimized several production workflows to reduce response times by approximately 28%.

Earlier, I developed full-stack business applications at Parallel Staf and responsive web applications at Boost. My work included APIs, database optimization, third-party integrations, and production improvements.
