Architected and led the development of Clinical Data Exchange Hub, a multi-tenant, cloud-native, event-driven SaaS application enabling secure, centralised medical data sharing across 500+ healthcare providers, reduced report turnaround time from days to near real time. Led the design and development of a high-throughput data plane management service to process multi-GB CSV/NDJSON datasets and ADT events from AWS S3 and OCI Queues. Designed partitioned, parallel processing pipelines integrating with Oracle HIE/Millennium/HDI systems, delivering near real-time demographic survey reports to customers via S3 and secure SFTP. Architected and implemented an inbound service to reliably process high-volume ADT events from Millennium EHR, streaming them into OCI Queues. Achieved fault-tolerant ingestion of millions of healthcare records daily, enabling downstream analytics and compliance workflows. Developed a low-latency outbound service using reactive stream architecture and non-blocking I/O to concurrently deliver patient data to multiple payer systems. Reduced end-to-end delivery latency by 70%, ensuring real-time data exchange and compliance with payer interoperability mandates. Architected and delivered a rules-driven Denial Management Service platform that transforms 835 remittance CAS data into structured, actionable denial objects using configurable CARC/RARC mapping, automated decision engines. Integrated the Denial Service with an AI-powered Denial Agent, enabling intelligent denial triage, automated appeal letter generation, and workflow orchestration through configurable denial categories and payer-specific templates. Built a scalable, configuration-driven, and audit-compliant revenue cycle automation solution leveraging agent-based architecture to improve denial resolution efficiency, reduce manual intervention, and accelerate A/R recovery.

Developed and deployed the Chargeback Deflector microservice, a backend component that automatically handles chargeback reversals from the Ethoca gateway, reducing manual intervention and payment loss in renewal workflows. Designed and implemented the 'Add Credit Card' feature for Prime users, improving user experience for repeat bookings and simplifying subscription renewals using CQRS pattern and A/B testing. Led the design and development of a new commerce rollout for the U.S. market, integrating with Worldpay for subscriptions under $10, enabling expansion into a new geography using A/B testing and Canary deployment.

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 VMware's legacy licensing model. 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 several minutes to seconds while ensuring compliance with subscription SLAs. Designed and developed a distributed onboarding service that decomposed subscription orders into atomic service-level requests, published them to Kafka for asynchronous processing, and coordinated workflow completion to automate subscription onboarding. Designed and implemented a Facade Service to orchestrate end-to-end subscription onboarding workflows and expose scalable APIs for UI-driven order management and lifecycle operations. Designed and developed core capabilities for VMware Aria Suite Lifecycle Manager, enabling automated end-to-end deployment, configuration, upgrade, patching, and scaling of VMware vRealize Suite components including vROps, vRA, vRLI, vRNI, and Cloud Proxies across private and hybrid cloud environments. Implemented state-machine driven orchestration workflows, vCenter API integrations, intelligent pre-validation checks, rollback handling, and topology-aware scaling to improve deployment reliability and operational efficiency. Reduced installation and upgrade time by 40% and deployment failures by 30%, with the platform successfully adopted across 100+ enterprise customer environments. Enhanced observability and resilience by integrating comprehensive telemetry (logging, metrics, alerts, dashboards) with CloudWatch, Wavefront, Pager Duty, and Slack notifications. Improved MTTR by 35% and enabled proactive incident response across production environments.

Developed scalable visitor queuing microservice for real-time chat platform responsible for queuing the visitor and allocate an agent to it for millions of users. Developed highly available, distributed and scalable CRM microservice for real-time chat platform which consumes the interaction events from Kafka and on completion of the interaction it fetches the transcript from the IHS service, finally it posts these transcript to the customer's CRM system by identifying the interacted user. Developed a MongoDB-backed pipeline for customer journey analytics, significantly improving data ingestion and diagnostic capability. Led development of a cryptographic framework using Vault by HashiCorp, supporting encryption-as-a-service and secure secret management. Engineered a self-service data aggregation and alerting engine used for omni-channel analytics reporting.

Developed access control features and automated review systems for RSA Identity Governance, supporting enterprise-scale user management and compliance.
