Vajra: Walmart's internal Kubernetes-based developer sandbox platform • Built and published an AI plugin with specialized agent skills that autonomously troubleshoot sandbox deployments, CI/CD pipeline failures, Kafka DNS misconfigurations and access issues, cutting developer support load by 20+ hours per week and resolving ~70% of common issues without escalation. • Architected cloud-native microservices (Java, Spring Boot, React, Kubernetes) with dynamic header-based routing, multi-node Kafka clusters and modular resource isolation, letting developers debug against any environment without full redeployments and cutting build-and-deploy time by 60%. • Integrated Grafana and Splunk with the sandbox platform, giving developers self-serve dashboards for service health, cluster metrics, deployment logs and pipeline status, with alerting on failed deployments, reducing average time-to-diagnose from ~45 minutes to under 10. • Engineered DAG-driven multi-service deployment pipelines with startup ordering, readiness probes, versioned Docker images and HashiCorp Vault secrets integration, improving ephemeral integration-test reliability by 30%. • Implemented Single Sign-On (SSO) across backend and front-end applications, strengthening security and reducing login time by 75%. • Automated parallel PR deployments via Concord CI/CD with auto-expiry and multi-cluster support, onboarding 15+ microservices, cutting environment provisioning time by 40% and boosting engineering velocity by 25%.
