SUMMARY

Database Administrator with Bachelor’s degree in Computer Science with 6+ years of experience supporting oracle databases (10g, 11g, 12c) and open source databases (PostgreSQL 1+ years) running on Linux, Unix, Aix, Solaris and Windows. I have also supported MS SQL databases (2008, 2012, 2014). Skilled at analyzing AWR, ASH, and ADDM reports in order to troubleshoot performance issues. Excellent in security management, database maintenance and establishing backup and recovery processes to safeguard data, paying attention to High availability configurations of the database as well as some PostgreSQL database activities like Replication. During this period, I have supported PostgreSQL databases where I migrated from Oracle to PostgreSQL. Supported 24/7 production and development environments. Support complete life cycle from Development, Test, QAT and Production. I am a proactive dba, a great team player, good in documentation, a fast learner and willing to learn more new things and make good use of them especially with the open source.
