About me
I'm a consultant with close to 20 years of experience in the databases field. I have led and participated in numerous projects involving MySQL, Oracle, MongoDB and SQL Server, across many well-known companies.
I'm also a developer, who contributed to two MySQL plugins, two custom MySQL DBaaS platforms, among other solutions.
In 2022, I founded query-optimization . com to help people understand and improve slow SQL queries.
