Case study

FastFreight Logistics

FastFreight had a fleet management system from 2011 that everyone was afraid to touch. Routes were planned by hand. Maintenance was reactive—trucks broke down constantly. They needed modernization without shutting down operations.

The challenge

The existing system was written in Classic ASP. No documentation. The original developers were long gone. Drivers hated the mobile app (a buggy iOS port of the desktop version). And management had no visibility into what was actually happening.

Our solution

We used the strangler fig pattern—built new components alongside the old system, then gradually migrated. New mobile apps for drivers, ML-based route optimization, predictive maintenance using vehicle telemetry. All while the old system kept running.
