Logistics Management Service & Dynamic Fields Service
Budget: $10 – $30 USD
I’m looking for a developer to build a logistics management system consisting of two microservices:
Logistic Service
Handles shipments (trackings) and order preparation (pickings).
Includes CRUD operations, state management (Kanban style), messenger assignment, notifications, PDF printing, and real-time updates via WebSockets.
Custom Fields Service
Adds dynamic, configurable fields to logistics records (similar to Notion’s custom fields).
Supports multiple field types, validations, filters, aggregations, labels, and versioning.
Project Requirements
Both services must be fully documented, including OpenAPI contracts and a detailed README.
All services must be containerized and run together with a single docker-compose file.
A Postman collection for testing is required as part of the final delivery.
Payment Terms
The project will be paid as a fixed-price project.
It has 2 main deliverables (one per microservice).
Each deliverable will generate a milestone payment upon successful completion.
Detailed project requirements are documented here:
