Executive Overview
Sawarga is a mission-critical municipal Super App serving 3.5+ million citizens across 50+ provincial departments. Designed to eliminate bureaucracy, it unifies public complaints, emergency services dispatch, and urban spatial analytics into a single responsive edge gateway.
Architectural Bottleneck & Migration
The legacy infrastructure relied on a centralized PHP monolith that experienced catastrophic lockups during public registration surges and spatial reporting events. By migrating to a Next.js Edge App Router architecture with PostGIS spatial indexing, query execution times dropped by 18x while handling over 10,000 concurrent geographic point lookups per second.
Key Technical Achievements
- Spatial R-Tree Indexing: Instant coordinate clustering for municipal incident heatmaps.
- Role-Based Access Control (RBAC): Strict multi-tenant boundaries for 500+ government officers.
- Zero-Downtime Deployment: Multi-region Docker container orchestration guaranteeing 99.99% public SLA.
