Working as a Database Expert, system integrator, software developer for many banking and telecommunication company in Vietnam, I gained experiences and knowledges of Storage, Networking, OS, Database, Application especially Database Administrator, Linux sysadmin, web development and shell scripting. I am certified (OCP 11g) Oracle database administrator with 9+ years experience in all DBA task. My expertise includes Installation, tuning, upgrading, patching, configuration, backup, restore, recover, design, security, data integration of database on *nix and Windows OS in single node, cluster, disaster recovery configuration. Beside it, I have experience about other type of database like MySQL, SQL Server, Sybase, MongoDB... I can provide complete service for your existing DB as well as install and configure your future database infrastructure. My favourite program languages are SQL, PL/SQL, PHP , bash. There are a lot of supporting tasks in system which require debug, tracing logs and troubleshooting, so my advantages are system support, configuration & customization, monitoring and fix problems. Additionally, I also work as a web developer. Sometimes I have to write custom report UI during integration phase, so Yii is my favorite PHP framework to quickly build the apps. Moreover, I also know how to code in HTML, CSS or to use Wordpress and Drupal to set-up websites. AngularJS is fine for me, too. I am always interested in new projects and look forward to speaking with you about how we can work together. Looking forward to hearing from you.
