Refactoring a global logistics system, cutting client response times by 80%
01.
A global logistics company needed a modern and faster platform
The client used a system that handled shipments, rate calculations, and tracking across many countries. Each region ran its own version of the code, which caused duplicated logic, slow updates, and long response times.
When Inspeerity joined the project, the main goals were clear. We needed to fix the existing system, clean up the code, and deliver one unified global platform.
We achieved this by:
- Updating legacy frameworks to modern .NET 6.
- Merging all regional systems into one global deployment.
- Reducing client response times from up to 30 seconds to only a few seconds.
- Integrating 20+ carrier APIs for rates, shipments, and tracking.
- Strengthening monitoring, logging, and security.

When modular growth becomes complexity
The platform connected e-commerce tools like Shopify, Magento, and WooCommerce with major courier networks.
It was built as a modular monolith by a previous partner. Over time, repeated code and inconsistent updates made the system hard to maintain and slow to scale.
This led to:
- Duplicate code in each regional version.
- Long response times.
- A mix of old SOAP services and newer REST APIs.
- Inconsistent logic and limited documentation.
- High effort needed to add new carriers.
The system had grown too large. The client needed a partner who could stabilize the live environment, improve the core structure, and restore performance without rebuilding everything from scratch.

How we delivered the solution
We started with a full review of the inherited codebase to understand data flows, modules, and integrations. Based on this, we introduced a cleaner and more stable architecture.
Refactoring and consolidation
Core modules were rebuilt in .NET 6 using a modular, service-based design. Regional deployments were merged into one global solution with shared logic for rates, shipments, and tracking.
Incremental improvements
Each part of the system was rebuilt and deployed in steps. This allowed the platform to run normally while quality and performance improved.
API modernization
Old SOAP APIs were replaced with REST to improve speed and reliability. Connections with couriers such as DHL, UPS, FedEx, TNT, and DPD were unified. Asynchronous calls and consistent error handling reduced delays.
Security, monitoring and performance
We added role-based access control, strong data protection, and improved monitoring with OpenTelemetry and AWS X-Ray.
Team and delivery approach
A small team of .NET engineers, QA specialists and a delivery lead worked closely with the client. They used an agile workflow with short Kanban cycles and regular user testing.

The impact
The refactoring project transformed the global logistics platform into a faster and easier-to-manage system.
- Response times reduced from 30 seconds to a few seconds.
- One unified platform replaced multiple regional versions.
- Better stability and performance during heavy daily traffic.
- Faster onboarding of new carrier APIs.
- Stronger security through role-based access and encryption.
- Full visibility with improved monitoring and logging.

Looking towards the future
The project ended with a stable, well-documented system prepared for the next stage of expansion. By focusing on refactoring rather than a full rebuild, the client avoided downtime and kept business running normally.
The new platform supports more carriers, scales more easily, and allows the client’s team to extend the system without major obstacles.
