Organized Projects

Program Integrity (POC) | Exafluence for Amida

Built a scalable Medicaid fraud detection pipeline for T-MSIS claims using Databricks, Spark, and Apache Iceberg with lakehouse architecture, implementing deterministic and graph-based fraud detection using FalkorDB to identify suspicious provider–claim relationships. Orchestrated metadata-driven ETL workflows across Bronze/Gold/Active layers using ExfHarmonize and Dagster, with results stored in PostgreSQL for analytics and reporting.

ExfHarmonize | Exafluence

Built a configuration-driven data engineering platform using Spring Boot and React.js for metadata management, ETL orchestration, and low-code pipeline design with multi-tenant support via Java SPI. Integrated distributed Spark execution across Kubernetes, AWS EMR, Azure, GCP Dataproc, and on-prem clusters, along with Keycloak-based IAM for RBAC and secure access control. Enabled document processing with OCR and search using Apache Tika and supported self-service analytics via Apache Superset.

SCMXPERT – Supply Chain Management Project using IOT Devices | Exafluence

Built an enterprise IoT-based supply chain management platform using Spring Boot and React.js, secured with Keycloak, to track and manage shipment workflows. Implemented real-time data ingestion using Confluent Kafka for IoT device streams, with scalable storage in MongoDB and AWS S3, and event-driven processing via AWS Lambda for automated document generation. Deployed the system on Kubernetes for high availability and integrated cross-cloud data transfer between AWS S3 and GCP GCS, delivering a production-grade solution for Dr. Reddy’s Laboratories.
