Who I Am

About Me

A full stack engineer who cares deeply about craft, performance, and the user experience.

Full Stack Developer with 6+ years building production web applications across Retail and Healthcare — owning everything from pixel-precise React/TypeScript UIs to Java/Spring Boot microservices and AWS deployments.

At Walmart, I'm part of a specialized team fine-tuning LLMs and building agentic AI workflows — including a multi-agent chatbot with real-time WebSocket streaming and autonomous API tool-use chains.

I'm passionate about clean architecture, accessible UI, and measurable impact. Whether it's cutting bundle size by 40%, boosting Core Web Vitals by 35%, or reducing dev effort by 30% through shared component libraries.
