We’ve spent a year developing Catawiki platform together. During this year Federico helped a lot to improve our operational database setup.
Deep knowledge of MySQL internals helped us tuning our production database servers performance. We’ve created a bunch of meaningful charts in Grafana. They explained important MySQL metrics in a simple manner. This effort helped us to achieve better transparency in the database topic.
Federico showed ability to talk to developers simply and efficiently. During organized company events and private conversations he was explaining them do’s and dont’s of working with RDBMS. This guidance resulted not only in countless refactoring improvements in our applications but also in several wiki articles presented to our developers.
