RomTelecom S.A.February 1997 - August 2013

There have been 2 periods. First, until February-2007, I worked in a service department for electronics applied in telecommunication. Here, I debugged many central units controlled by microcontrollers. All those modules were built using SMT technologies. In addition, I designed a certain number of units for control, controlled by microcontrollers from Atmel. In this department, I designed programs in assembler language, having the role to control the technological processes. For these controllers, I designed PCBs, electrical schematics and/or software firmware.

The second period from February-2007 to september-2013. Maintenance, configuration of SDH national network. Creation, of new services , E1, STM1, STM4 and STM16, for the company’s customers. Performance analysis. Topology analysis for developing new works. The equipment belongs to multiple producers: Alcatel, ECI, Huawei, SIAE, Fujitsu, Ericsson, Marconi. Permanent surveillance and maintenance of the servers’ network which administrates whole SDH networks. I have knowledge in Unix-Solaris to maintain some applications, and managing the applications. In 2011-2012 I restored a cloud of servers for a national network SDH Fujitsu, starting and finalizing a project in this direction.
