I need an experienced Java engineer to add a complete geofencing module to my existing Spring Boot backend. The core tasks are to detect enter, exit and dwell events in real time, expose the necessary REST endpoints and wire everything up to Google Maps API for geocoding and polygon handling. You will be working against a mature code-base that already manages users, devices and location pings. Your part is to design the geofence data model, build the event engine, and surface webhook or message-queue notifications that the rest of the platform can consume. Because this feature is a priority release, I would like to see it live as soon as possible ideally within the next couple of weeks. Please share relevant past work that proves you have shipped similar location-aware services, especially if you have done so with Spring Boot, Hibernate/JPA and Google Maps. If all goes well, there is room to extend the contract for additional location analytics work. Responsibilities :- ● Design and implement backend logic to manage geofences, user coordinates, and real-time event triggers ● Integrate with third-party geofencing / mapping APIs such as Mapbox, Radar, HyperTrack, or similar ● Develop REST endpoints to create, update, retrieve, and delete geofences ● Implement webhook handlers or real-time listeners for enter/exit/dwell events ● Optimize accuracy and performance of real-time location tracking ● Create scalable backend architecture and database schema for location logging ● Coordinate with frontend/mobile team for testing and validation ● Provide technical documentation Required Skills :- ● Strong experience with Java & Spring Boot

Hi there, Java/Spring Boot backend engineer here with strong experience building real-time, location-aware services and geofencing modules. I’ve previously implemented: A geofencing engine for fleet tracking that detected enter/exit/dwell events in real time and pushed them via webhooks + RabbitMQ to downstream services. A Spring Boot + JPA backend that integrated with Google Maps (geocoding, reverse geocoding, polygons) and Mapbox for visualizing dynamic delivery zones. Scalable location logging schemas optimized for high write volume and querying user/device movement history. For your project, I would: Design a Geofence data model (circular/polygonal, schedule, tolerance, metadata) tied to existing users/devices/location pings. Build an event engine that tracks last-known fence state per device and computes enter, exit, dwell transitions in real time. Integrate with Google Maps API for geocoding and polygon handling, with abstraction to support Radar/Mapbox/HyperTrack if needed. Expose REST endpoints to CRUD geofences and query event history. Implement webhooks or message-queue publishers so the rest of your platform can easily consume events. Provide clear technical documentation and collaborate with your frontend/mobile team on test scenarios. Happy to adapt to your current architecture and coding standards and focus purely on shipping a clean, extensible geofencing module.

I can design and implement a complete geofencing module on top of your existing Spring Boot backend so you get reliable enter/exit/dwell events in real time. Here’s how I’ll approach it: Data model & schema: Design Geofence, GeofenceAssignment, EventLog, and LocationPing relations using JPA/Hibernate, optimized for fast geo lookups and history. Event engine: Real-time processing of location pings to detect enter, exit, and dwell (with configurable thresholds), built as a clean service layer that plugs into your existing device/user model. Maps integration: Use Google Maps (and/or Mapbox/Radar/HyperTrack where useful) for geocoding, polygons, and point-in-polygon checks. APIs & notifications: REST endpoints to create/update/delete/list geofences, plus webhooks or queue-based notifications (Kafka/RabbitMQ/Redis Streams) for downstream consumers. Performance & accuracy: Caching, batching, and clear tolerance rules to reduce noise while keeping events responsive. Docs & handover: Technical documentation and collaboration with your mobile/frontend team for end-to-end validation. Target: a production-ready module within a couple of weeks.

To design a robust geofencing module, I recommend first structuring the geofence data model to efficiently track user movements and events. This approach ensures optimal performance and accurate event triggers. I have successfully built similar location-aware services using Spring Boot, Hibernate/JPA, and Google Maps. In my previous project, I developed a geofencing solution that processed real-time location data, integrated seamlessly with the Google Maps API, and provided REST endpoints for effective management. Here’s how I can help: – Design the necessary database schema for managing geofences and user coordinates. – Implement the event engine for real-time notifications, including webhook handlers for enter, exit, and dwell events. – Optimize tracking accuracy while ensuring seamless integration with your existing codebase. I am committed to delivering this high-priority feature within your timeline. Let’s discuss how we can bring this project to life.
