What we built

  • three Node.js microservices (customer, admin, payment) backed by PostgreSQL on AWS ECS Fargate
  • Android and iOS investor apps featuring OTP login (domestic + international), investment portfolio, KYC document upload, Statement of Account PDF download, site image galleries with DRM-style screenshot prevention, payment history, push notification deep-linking, and force-update mechanisms
  • a Channel Partner portal with Convox dialer integration and invoice management
  • full CRM migration from Microsoft D365 to Salesforce covering leads, projects, launch phases, inventory buckets, promises, and emergency liquidation APIs; and
