Overview

Architected and developed a comprehensive ERP system spanning four microservices - Immigration, Accounting, Trucking and Entity Formation. Designed scalable AWS cloud infrastructure integrating eight services and implemented a hybrid database approach with PostgreSQL and DynamoDB.

Challenge

Traditional ERP systems lack the flexibility to manage diverse business lines with unique workflows. The client needed one unified platform for Immigration services, Accounting operations, Trucking fleet management and Entity Formation.

Solution

Designed the complete system architecture across four microservices with React 18, TypeScript, Node.js 20, PostgreSQL, DynamoDB and MeiliSearch. Built gRPC-based inter-service communication with 60% reduced latency, plus real-time features via Socket.IO and GraphQL subscriptions.
