Incidema - Perhutani Apps | Project Case Study

#Incidema - Perhutani Apps

##Architectural Overview

Incidema is a straightforward digital platform tailored for forestry management officers to report and map forest-related incidents. As a Backend Engineer, I established the data pipelines to collect mobile location reports, distribute them to regional admins, and surface those insights on interactive dashboards.

##Key Features

Location-Based Reporting

Direct integration allowing field officers to pin their location and submit visual incident logs.

Interactive Incident Heatmaps

Map interfaces grouping high-frequency report areas to guide daily patrols.

Super Admin Dashboards

Broad administrative views for recapitulation reports, data aggregation, and account management.

Push Notifications

Instant mobile alerts sent to area commanders when a severe issue is mapped.

##Engineering Highlights

###Event-Driven Reporting

To manage spikes in incoming reports reliably: - Message Broker: Channeled incoming mobile data straight into an Apache Kafka queue, preventing database deadlocks when multiple officers report from areas with poor signal simultaneously. - Flexible Schema: Used MongoDB alongside the spatial logic to hold unstructured text descriptions and varied image payloads safely.

##My Role and Responsibilities

API Design: Scaffolded the Express.js and Restify endpoints connecting the mobile clients to the backend queue.
Data Persistence Strategy: Connected the Kafka consumers directly to the MongoDB collections for clean, steady writes.
Authentication: Integrated basic secure JWT session handling for super admins.
Notification Loop: Hooked up Firebase FCM to the backend, triggering specific topic-based alerts depending on report severity.
