   Dec 2021 — Present · Bentonville, AR, US

   As a Senior Software Engineer at Walmart/Sam’s Club, I lead the design and development of scalable, cloud-native enterprise solutions that power core membership, checkout, and payment platforms serving millions of customers daily. My work focuses on building resilient microservices, optimizing distributed systems, and automating deployments across multi-region environments.I have architected and implemented Spring Boot microservices integrated with Apache Kafka, GraphQL, and Cosmos DB, driving real-time event processing and improving data consistency. I deployed these services on Azure Kubernetes Service (AKS) and Walmart’s internal Cloud Native Platform (WCNP), leveraging Concord YAML and Looper Pro pipelines to automate CI/CD workflows, ensuring seamless and traceable deployments.My responsibilities include developing secure, high-performance APIs using Spring Security, OAuth2, and JWT, integrating Venafi-based certificate management, and improving system performance through Apache Ignite caching and optimized queries in Cosmos DB and PostgreSQL. I’ve implemented Camunda workflows to automate business processes and ensure compliance while collaborating closely with product, QA, and DevOps teams to enhance delivery velocity and system reliability.I also mentored junior engineers, championed clean architecture, SonarQube quality gates, and Git branching standards, and drove continuous improvement across development and deployment pipelines. Through these initiatives, I’ve helped modernize legacy systems into high-performance, event-driven microservices, significantly improving scalability, operational efficiency, and customer experience across Walmart’s digital ecosystem.
