Freelancer profile translated to English.

Description

I have over 25 years of experience in database management, including PostgreSQL, DB2, SQL Server, Oracle, and Sybase, with expertise in optimization, installation, upgrades, backups/restorations, cluster setup, and technical consulting.

In recent years, I have specialized in performance optimization on SQL Server, Oracle, and PostgreSQL, while developing solid experience in PostgreSQL training.

My development skills (PL/SQL, Transact SQL, Shell, Perl, Java, PowerShell, Python) allow me to automate and optimize daily tasks effectively.

I am perfectly proficient in Windows, Linux, and AIX environments, enabling me to perform relevant analyses adapted to each context.

I am comfortable working both independently and in a team, and I always prioritize customer satisfaction.
