VmwareMay, 2021 - Aug, 20232 yr 3 months
Led architecture and development of vRealize Cloud Subscription Manager, a multi-tenant, distributed SaaS platform managing end-to-end subscription lifecycle (order intake, onboarding, service activation). Applied Event Sourcing and Saga patterns to ensure resilience and consistency at scale, enabling seamless onboarding of thousands of enterprise customers and retiring VMwares legacy licensing model. Designed and implemented a Facade Service to orchestrate subscription onboarding workflows and expose APIs for UI-driven order management. Built a scalable subscription service to automate activation of bundled services across multi-cloud environments, ensuring error-free provisioning at scale and removing manual activation effort for ops teams. Architected a low-latency Orchestrator to execute complex service activation workflows, applying rule-based execution per service type. Optimised for concurrency and throughput, the system reduced activation time from hours to minutes while ensuring compliance with subscription SLAs. Designed and developed installation, upgrades, and scaling (horizontal/vertical) process for VMware vRealize Suite (vROps, vRA, vRLI, vRNI, cloud proxies) via state-machine patterns and vCenter APIs, cutting installation/upgrade time by 40% and reducing deployment failures by 30% through intelligent pre-checks - adopted across 100+ enterprise customer environments. Enhanced observability and resilience by integrating comprehensive telemetry (logging, metrics, alerts, dashboards) with CloudWatch, Wavefront, PagerDuty, and Slack notifications. Improved MTTR by 35% and enabled proactive incident response across production environments.
