RTKu

The Problem

Neighborhood association (RT) management is often still handled manually, including the payment of monthly dues. This causes inconvenience for both the administrators and the residents.

The Solution

RTKu is an integrated housing and financial management system that connects property managers with residents through a single platform. It is built using REST API architecture (Laravel) and a modern frontend (React + TypeScript).
