About Me
I'm a Senior AI Software Engineer with 8+ years of experience designing and delivering scalable AI applications, cloud-native systems, and SaaS platforms across healthcare, real estate, and enterprise environments.
My expertise spans LLM-powered applications, RAG architectures, AI agents, and intelligent automation. I specialize in integrating foundation models including GPT-4/5, Claude, Gemini, Llama, and AWS Bedrock into production systems that serve enterprise users at scale.
Currently based in Chicago, IL, I build production-grade solutions using Python, FastAPI, React, TypeScript, and cloud platforms—delivering systems that combine technical excellence with real-world business impact.
