How we went from legacy, complex and slow software to new, speed, resilient and maintainable software. I'll start the talk showing the problemas and the challenges that my team had received. After that, I'll show the tests, tests of performance and the options that we did considering technologies and strategies of development. The difficulties and problems also will be show.
