Multi-Tenant Water Supply Management Platform – Full-Stack SaaS ERP Module for Public Infrastructure

Led the full-stack architecture and development of a government-grade utility management system built for multi-tenant deployment across local water authorities. The platform replaced a legacy Java desktop application with a modern, cloud-based system built using .NET Core, Angular, MySQL (EF Core), Android (Kotlin), and JasperReports — enabling document-driven workflows, role-based approvals, live metering, billing, and mobile operations.
