What I'm looking for

I'm looking to build reliable production AI and full-stack systems where I can solve ambiguous problems, improve performance, and collaborate across teams.

At Bank of America, I build production AI systems and secure digital banking services, including agent experiences that increased user engagement by 20% and forward-deployed engineering practices that improved deployment efficiency by 30%.

I've also delivered enterprise retail platforms at Walmart using React, Node.js, GraphQL, Docker, and Kubernetes, and built Java/Spring services at Cognizant. My work spans reliable APIs, event-driven systems, CI/CD automation, AI agents, and ML/AI judgment frameworks, with a focus on performance, quality, and scalable customer-facing software.
