About

Building intelligent systems, not demos

AI Systems Engineer with 6+ years building production software and AI platforms at Walmart and Sears. I specialize in architecting Agentic AI systems that combine LLMs, APIs, distributed services, vector databases, orchestration frameworks and modern web applications into intelligent business products. Passionate about designing AI systems that automate real-world enterprise workflows rather than standalone AI demos.
