Worked as team member that developing Main Station, which is C++ based software for network modeling, planning, designing. Tasks have been worked on- Maintain/improve nightly build (shell script)- Create and implement auto-test cases (C++ & expect script) Highly appraised for what I have achieved - often caught the fresh break right after the nightly full build by auto test cases.- Take full responsibility for Network Traffic Baseliner -- one important module of the Network Planning application that provide the network utilization and trend ( C++, CMU/SNMP )
