Tech Lead \| Walmart \| 11 years in Distributed Systems \| AI & Scalable Architecture

## About

I'm a Senior Software Engineer & Tech Lead with 11 years of experience building scalable backend systems and distributed microservices for high\-traffic enterprise platforms\. I enjoy solving complex engineering problems—whether that's designing systems that process millions of transactions, improving API performance and reliability, or leading teams to deliver production\-ready software at scale\. Over the years, I've worked across cloud platforms \(AWS, GCP, Azure\) and built systems with a strong focus on scalability, resilience, and maintainability\. More recently, I've been exploring AI\-powered engineering, designing agentic workflows that automate repetitive tasks, improve developer productivity, and streamline business processes\. Core technologies: Java • Spring Boot • Microservices • REST APIs • Distributed Systems • System Design • AWS • GCP • Azure • CI/CD Beyond writing code, I enjoy mentoring engineers, driving architectural decisions, and collaborating across teams to turn complex ideas into reliable, scalable products\.
