About

As a backend-focused software engineer with over 12 years of experience, I currently serve as a Lead Software Engineer at Walmart, where I specialize in backend architecture, microservices, and platform migrations. My work emphasizes designing and scaling distributed, cloud-native systems, with a strong focus on availability, cost optimization, and operational efficiency. At Walmart, I lead initiatives such as migrating Sam’s Club E-commerce domains to a unified platform and consolidating backend services to reduce infrastructure costs. With a hands-on approach to Spring Boot, Kubernetes, and governance of GCP, Azure resources, I contribute to the delivery of high-traffic commerce flows while achieving significant cloud cost savings. My commitment lies in creating resilient, scalable systems that address real-world business challenges.
