    I performed the test design and man-hour management as the leader of mobile phone career's NIX-based system testing team.
    The main task is to create and send HTTP/IMAP packets to test, which I spent most of my time on. This made me understand what protocol headers mean only by seeing binary patterns.
    Experiencing this kind of project management such as man-hour calcuration and resource management, it led me to step into the next career forward.

    I built up my next career at a start-up company providing ther own services for call center system.
    Managed to cover all the procedures; including server kitting, intalling in data centers to network design and construction, application development, customer support.
    For call center system, extremely high application response speed and seamless sound quality without latency or dropping are always required.
    In order to build and maintain such robust system, I have performed comparative verification of network devices/providers, as well as thorough application performance improvement.

    Also, I gained the skills of application deployment with Redis to improve response from MySQL, construction/management of IP-PBX with Asterisk, and load valancer deployment with LVS. Especially, the experience in managing containers with LXC prior to Docker gave me a firm basic knowledge of up-to-date technology such as cgroup/namespace.
