I worked on a system for a large automotive corporation, designed to support over 100 factories across all continents. The goal was to create a solution that was fast, scalable, and could handle large amounts of data in real-time.

The system was built using asynchronous programming, which means it can process many tasks at once without slowing down. This helps the system stay fast and responsive, even when dealing with a lot of requests at the same time. It also uses an event-driven approach, where different parts of the system can "listen" for events and react to them as needed, helping everything stay connected and synchronized.

One of the biggest challenges was understanding the complex business logic behind the system. I worked closely with the team to break down and understand how the system needed to work for the company. This allowed me to design the solution in a way that met both the technical and business requirements, ensuring the system functioned smoothly across all locations.
