DHL UK Returns
Peak-season parcel returns for a logistics estate that had to hold holiday volume: .NET microservices, containers, and Kafka on Linux, built for security and controllable scale.
What the returns estate had to survive
DHL Parcel UK needed a returns system that would survive holiday peaks without sacrificing security or operability when the network was busiest. Scale and reliability were not optional extras; they were the reason the project existed.
What shipped into production
A microservice architecture in C#/.NET, deployed with Azure DevOps and Docker onto an on-premise Linux estate and linked with Kafka message queues. The design favoured robustness, security, and controllable scale, and the work finished to specification ahead of schedule.
Why this sits under fixed-scope Build
Peak returns volume is a finish-line problem with a dated window. Localhost held delivery accountability for the services that had to be live before the busiest weeks, with security and operability treated as part of the same done definition rather than as a follow-on wish list.
