I'm offering
I've been working with relational and NoSQL databases (SQLite, MySQL, MariaDB, Percona Server, PostgreSQL, MSSQL, MongoDB, and Cassandra) for more than 15 years. During all that time I have used Python for database automation, ETL processes, industrial devices integration, web scraping, etc...
On the other side, I've been involved in large as well as small projects, so I can easily adapt to the work needs in a very short time.
Having said that, I believe that I can fulfill any project requirements very well.
Please do not hesitate to contact me at your earliest convenience so we can discuss further details.

Functions. DBA (implement, administrate, design, replicate, migrate, tuning, monitoring, backup recovery, security, scripting and high availability/clustering) for all database environments (SYBASE ASE, SYBASE IQ, SQL Server, MySQL) installed in two data centers (1500 servers and 2000 databases, 2000 Tb of storage capacity and 2000 communication lines), servicing several branches in the company (Spain, France, Portugal, Chile and Brazil).
Key Achievements.
• To improve response to disaster recovery situations, we split our production environment into three different scenarios (primary, secondary and tertiary). Transactions are now replicated from primary to secondary and tertiary scenarios. I was responsible for re-designing our database architecture as needed, setting up, configuring and implementing replication, installing all database instances in secondary and tertiary scenarios, and defining security specifications.
• As part of the same project, we put in operation a second Data Centre, installed in a different building. I was responsible for the project coordination, installation of all database instances and operating system installation (windows and Linux) of several servers (more than 800).
• Redesign the database architecture in order to convert the software from our main production system to a multi-country platform.
