MySQL Guru“Johann was a great Database Architect. We were very worried about our application's performance going into the project because of the complex data organization and the sheer amount of data. Johann quickly stepped in and put us at ease. He worked hard to really understand our data and asked all the right questions. During the app development, Johann continued to tune and optimize the database to ensure peak performance. Our application turned out great. It was fantastic to be able to focus on the development and let Johann take care of the data. Great work, great communication and great accountability all around! We will definitely work with Johann again.”
