I'm working on refactoring an auto-assigner application that's responsible for getting food orders from clients and assign it to the most proper biker available to deliver the food.
It's a part of a legacy monolithic core written in PHP, Symfony and I'm porting it to Python.
The most exciting part of this transmission is a timescale database, that's responsible for storing current bikers' position and its performance on huge amount of data (500M+ records) is just mind-blowing.
