Working as a support engineer, software developer and system integrator for many telecommunication systems in Vietnam, I gained experiences and knowledges of VoIP, PSTN, mobile networks and IP networks, especially Linux sysadmin, web development and shell scripting.
My favourite languages are PHP, perl, bash. There are alot of supporting tasks in telecommunication 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.
Looking forward to hearing from you.
