Multi-tenant cloud ERP for car-rental operators

ASP.NET CoreAngularPostgreSQLDocker

The problem

Car-rental operators in the region were running on spreadsheets, WhatsApp, and aging desktop apps — losing visibility on fleet, contracts, and accounting.

The approach

Modeled the rental domain (fleet, contracts, customers, accounting) as a first-class core, with framework concerns at the edges.
Built a multi-tenant ASP.NET Core backend with strict tenant isolation and per-tenant configuration.
Shipped an Angular operator console with offline-resilient flows for branches with shaky connectivity.
Containerized the whole stack and ran it on a small fleet of nodes with automated backups and observability.

Architecture

Outcomes

Live production workloads handling real rental contracts every day.
Sub-second response times on hot operator paths under realistic concurrency.
Zero-touch deploys: push to main → image build → environment promotion.
