Telecom GIS

This field data collection application is designed to transform how telecom teams manage and capture on-ground asset information with accuracy and efficiency. Built with a user-friendly interface, it enables organizations to easily assign surveys, construction tasks, and other field-related activities to team members. By digitizing the entire workflow, the app eliminates manual processes and ensures that all field operations are structured, trackable, and streamlined. The platform allows field users to capture and update data directly from the site using integrated map functionalities, ensuring precise location tagging and real-time updates. This reduces errors, improves data reliability, and ensures that the central database always reflects the most current information. Whether it’s asset verification, site surveys, or infrastructure updates, the app provides a seamless way to manage and validate field data efficiently. In addition to data collection, the system supports smooth integration for analysis and reporting, enabling teams to derive actionable insights from field operations. Managers can make informed decisions based on accurate, real-time data, improving overall operational effectiveness. Ideal for telecom and infrastructure teams, the app enhances productivity, saves time, and elevates field operations by delivering a smarter, more connected data management experience.

Challenges & solutions

The technical problems our team solved to ship a reliable, unified mobile experience.

Render thousands of high-precision spatial entities on a mobile map without causing frame drops or memory leaks, while accurately tracking user locations.

Engineered a map rendering architecture using `google_maps_flutter` with spatial filtering and cluster rendering techniques. Built a dynamic layer manager (`network_layer.dart`) that handles polygon and polyline draw buffers efficiently, integrating `geolocator` filtering to capture accurate asset coordinates with real-time GPS correction.

Coordinate multi-stage installation workflows and permit checklists in zero-signal zones without losing progress or verification states.

Designed a robust state machine utilizing `easy_stepper` and GetX reactive controllers, coupled with local storage caching. Integrated `mobile_scanner` for barcode/QR validation of hardware assets, enabling the app to complete BOM audits and stage transitions offline, queuing API payloads to sync to the server when connection is restored.

Upload high-resolution media reports under weak network signals without causing request timeouts, high battery drain, or bandwidth costs.

Implemented an automated media processing pipeline using `flutter_image_compress` and `video_compress` that downsizes assets on-device before transmission. Developed a custom background upload queue with `dio` that uses chunked uploads, network-adaptive rate limiting, and automatic retry policies on connection failure.
