À propos de moi
Senior Database Administrator with 3+ years running production databases: Oracle, SQL Server, PostgreSQL, MySQL, MariaDB and MongoDB. I’ve managed 50+ servers for clients in Latin America, the UAE, Oman and Saudi Arabia, and ran the databases behind a high-volume payments platform at 99.9% uptime. I fix slow queries, set up backups that actually restore, and migrate databases with minimal downtime, including to AWS RDS. Send me your database engine, version and the problem you’re seeing.
