Oracle DBA specializing in high-availability banking systems, performance tuning, and automation.
EthiopiaI am an Oracle Database Administrator with over three years of banking experience managing Oracle 12c and 19c production environments supporting core banking systems.
I specialize in RAC and Data Guard administration, RMAN backup and recovery, performance tuning using AWR/ASH/ADDM, and database security and auditing to meet regulatory standards.
I designed and automated an ETL pipeline handling ~100k+ daily financial transactions, improved migration reliability to near-zero failures, and strengthened DR readiness with documented recovery procedures.
I also bring hands-on experience in Linux/Solaris administration, shell scripting, and prior full-stack systems engineering (PHP/Yii2/MySQL), which helps me coordinate cross-functional teams and deliver reliable enterprise solutions.
