Strangling the Monolith: Transition to High-Performance FastAPI
Modernizing the logistics core of a transport giant. We decoupled a 10-year-old legacy system into async microservices using Python.

The Legacy Monster
The platform calculated routes in async queues taking minutes under high load.
The Strangler Fig Pattern
We applied the strangler pattern, surrounding the monolith with highly optimized FastAPI microservices.
Impact
The system now supports 10x more concurrent requests while using half the cloud compute.
