I'm a telecommunications engineer with more than six years of experience in multiple branded NGN networks, hands on operation, maintenance, and configuration of Cisco routers and switches, Huawei routers, switches, softswitch, universal media gateway, Tektronix spectra, acme packet Session border controller and wireshark. I am a very fast learner, on my entry to Huawei I did not know anything about VoIP or anything regarding the technology, but a week later I was the best Engineer at the NOC and they ask me to made a presentation for the customer Comcel, in which everyone congratulate me, I also learn Excel Macros for making statistical reports from RAW data obtained from the platform, And configure a CentOS Radius authentication server for the platform. All of the above without former instruction and those were my ideas to improve security and leave tedious work of copying and pasting information to an Excel spreadsheet. I was in charge of the platform security giving and configuring all the security policies for each equipment in the platform, I wrote the manual for doing this, so anyone could do it after.
