I will take care of database systems

I am a highly experienced Database Administrator (DBA) with over 8 years of dedicated experience ensuring the high availability, performance, and security of critical database systems, including Oracle, MySQL, PostgreSQL, and MSSQL. My expertise spans the complete database lifecycle, from architecture design to advanced tuning and disaster recovery across heterogeneous environments.

Oracle Mastery: I am an expert in Oracle (12c-21c) encompassing installation, patching (CPUs, PSUs), and upgrades. I possess expert-level proficiency in RMAN for complex backup/recovery (including PITR and ZDLRA), and am skilled in Performance Tuning using AWR, ADDM, ASH, and execution plan analysis. I design and manage High Availability solutions, including Oracle RAC and Data Guard (Physical/Logical/FSFO), and implement robust security (TDE, Database Vault). I am proficient with Multitenant (CDB/PDB) and Cloud (OCI/Autonomous) technologies.

Cross-Platform Expertise: I provide full administration (installation, configuration, upgrades, backup/recovery) for MySQL, PostgreSQL, and MSSQL. This includes HA/Replication setups like MSSQL Always On and PostgreSQL Streaming Replication, and query optimization
