About

At Razor Group, I work on data infrastructure and multi-channel commerce. Most of my work sits at building ETL/ELT pipelines enabling downstream services to access accurate, real-time data, and developing solutions to fan-out products across multiple sales channels — Amazon, Walmart, eBay, and Shopify. Also worked on order processing workflows: syncing ERP systems, assigning courier partners, and managing warehouse shipments end-to-end. At Accenture, I did backend engineering for Cigna Healthcare — built and maintained the Provider, Customer, and Individual microservices powering eligibility verification, claims retrieval, and policy management for healthcare providers and the myCigna app. Designed downstream data pipelines into OpenSearch with index mappings and normalized schemas built around query access patterns, significantly improving search performance for read-heavy workloads. Infrastructure provisioned in Terraform. At Srijan, I worked on Vimient — a real-time IoT health monitoring platform . Built microservices and cloud-native components to process real-time streaming data from IoT devices, developed ETL pipelines to integrate and normalize data from external vendors, and built the notification and incident reporting system that triggered real-time alerts for caregivers and users. Also developed the backend services powering data access for web and mobile clients. I have had strong ownership of end-to-end data systems, from ingestion and processing to monitoring production support focus on scalability , fault tolerance and operational excellence.
