Description

Hello and welcome to my profile!

After working directly for MySQL and MariaDB companies as a consultant, I now operate independently through my company OceanDBA:

I am available for consulting/expertise missions on MySQL, MariaDB and the entire ecosystem (Percona, Galera, ProxySQL, Columnstore, Vitess, MaxScale, Sphinx ...).

I can also help you in defining web platforms and administering Linux servers.

Since 2009, I have been carrying out remote and on-site missions every week (worldwide):

- Database health check audits

- Performance analysis and improvement

- High availability audit and recommendations

- Problem analysis and resolution

- Advice on implementing backup strategies

- Version upgrades and migrations

- Training (DBA Administration, MySQL Performance, MariaDB High Availability, Galera Cluster, ProxySQL ...)

98% satisfaction among nearly 1000 clients (References available)

Do not hesitate to contact me to discuss your needs,

Joffrey
