AC-CORE replaces reactive legacy infrastructure management with a proactive digital platform. Engineered for the local government of Angeles City, it connects everyday citizens directly with engineering departments to report hazards like clogged drains and road erosion. The system utilizes geospatial mapping and live environmental syncing to predict and prevent severe downstream flooding.
Explore the live production application or review the codebase on GitHub.
Allows citizens to log emergencies quickly using a Guest Reporting mode. The system utilizes Auto-Detect GPS for precision and includes a visual status timeline (the Pizza Tracker) so users can see exactly when their report is resolved.
Integrated the OpenWeatherMap API to automatically attach real-time rainfall and temperature data to every hazard report. This provides city engineers with immediate environmental context during monsoon storms.
A desktop dashboard featuring an interactive Leaflet map with MarkerCluster. Administrators can view active hazards, access the integrated 24/7 emergency directory, and export CSV reports for urban planning.
The primary challenge was designing a robust geospatial tracking application within a strict one-week academic sprint. The system needed to process high-resolution photo evidence and plot thousands of map markers without crashing browser threads on low-memory mobile devices.
Because this platform is designed to handle sensitive municipal data and emergency spikes, security and speed were heavily prioritized during development:
The admin portal is secured using JSON Web Tokens (JWT) and Bcrypt password hashing. Citizens can access the portal seamlessly using secure Google OAuth 2.0 integration.
Implemented Express Rate Limiting and Helmet middleware on the Node.js backend to protect the municipal database from malicious spam reporting and external attacks.
Leading the development of AC-CORE demonstrated my ability to architect complex full-stack solutions under extreme time pressure. Translating a real-world bureaucratic problem into a highly optimized, map-driven application proved the direct impact that thoughtful software engineering has on public safety and infrastructure.
