Cosa dicono su Vettabase e Federico Razzoli.

Vettabase performed a remote health check of our MariaDB cluster and MaxScale database proxy. The cluster is a critical infrastructure component for many of our experiments at the synchrotron. Vettabase produced a detailed report with all identified issues and recommended solutions for each. The report has given us reassurances about our database health and will serve as a guide for future improvements. Vettabase has demonstrated a deep technical understanding of MariaDB, Galera and MaxScale in a Linux environment. It was a pleasure to work with them!
At Currencies Direct, Federico reviewed our Cassandra infrastructure, providing us with precious recommendations on how to improve its configuration and our data models. His consulting clarified the intricacies of a distributed database and the Java Virtual Machine, and allowed us to take advantage of the peculiarities of Cassandra.
I would recommend Federico to other companies to handle their database problems.
Federico’s ability to explain high level concepts in a clear, concise fashion has saved me countless hours educating developers. It is one thing to explain a concept in depth to an audience of one, it is quite another to make clear the same information in a way everyone can understand.
His willingness to contribute to the overall knowledge base is a credit to the open source community.
In a time when so many people call themselves ‘full stack’ or ‘subject matter experts’, Federico is indeed just that. He has the respect and gratitude of his peers, colleagues, and customers alike.
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 manneer. 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.
Federico is a consultant who is extremely familiar with the entire MySQL ecosystem, and the LAMP stack, among other things. Federico has contributed source to Flexviews, part of the Swanhart Toolkit, and has tested my software extensively, offering bug reports and authoring code to fix problems and improve test cases. I would trust Federico to work on my systems, which is a trust that I extend to very few. He is an excellent engineer that I would be proud to have in any team that I work with.
