At VISPIRON as BMW Group partner, I was responsible migrating the old legacy monolithic web in old PHP developed to manage internal BMW car sharing and leasing to modern microservice architecture using Java Spring Web application. As a result BWM could
1. See the improvement of the web user satisfactions
2. Administration applied therefore could able to help passengers in emergency situations by frequently checking the safety of the car telemetry information.

3. Reduced the CO2 emission by %2.4 at the first launch as user telemetry car's info helped car to adjust the speed and acceleration accordingly.
4. Encouraged to use green energy based car products and also electric cars.
