Bejagung — Community Management Platform

Everything used to be recorded in handwritten notebooks. bejagung.web.id was born from a real need: designing and building a unified web platform now used to manage RT residents, prayer group finances, haul genealogy data, and local UMKM business profiles — all in one system with a multi-tenant architecture.

Architecture

Built on the Inertia.js SPA pattern — Laravel 12 on the backend paired with React 19 + TypeScript on the frontend, with no separate REST API. On top of this sits a multi-tenant system supporting three data isolation strategies (shared table, separate database, schema) within a single codebase, without changing business logic across models.

The hardest technical challenge: designing a financial system where data cannot be deleted. Every correction generates a void + reversal entry — preserving full data integrity and audit trail, following professional accounting standards.

Highlights

• 🏗️ Multi-tenant — one codebase, three data isolation strategies (shared table / separate database / schema)
• 📒 Immutable financial ledger — corrections via void-reversal, never delete, full audit trail
• ⚡ Real-time — WebSocket powered by Laravel Reverb, no paid third-party services
• 🔐 Granular RBAC — per-feature permissions using Spatie Laravel Permission
• 📱 PWA — browser push notifications, offline mode, installable
