Experienced Database Administrator skilled in MySQL, MSSQL, and Oracle with automation focus.
PhilippinesWhat I'm looking for
I am a Database Administrator with over three years of hands-on experience managing MySQL, Microsoft SQL Server, and Oracle (10g/11g/12c) environments for enterprise systems. I specialize in performance tuning, backup and recovery (RMAN, DataPump, SQL Server Maintenance Plans), and automation using PowerShell, Batch, and Bash scripting.
At Magsaysay Shipping and Logistics I administered MySQL and MSSQL databases for WMS and logistics systems, led MSSQL migrations, implemented optimized backup strategies, wrote automated backup and monitoring scripts, and improved database performance through query and index tuning. At Metrobank Trust and Company I managed Oracle RMAN/DataPump backups and recovery, performed performance tuning with Oracle Tuning Advisor, supported Oracle RAC, and automated DBA tasks with shell scripting.
I prioritize reliability, automation, and clear documentation, and I collaborate closely with developers and operations teams to improve database design, implement audit logging, and resolve production incidents. I am seeking opportunities to further grow technically while contributing to stable, high-performing database systems.
