Kinh nghiệm

Chief electronic Engineer

ASPiSYS Ltd
thg 3 1997 - Hiện tại
I have worked for ASPiSYS ltd since the birth of the company, being responsible for the designing of all the projects hardware part. During all those years, I have done many designs from scratch, covering almost all spectrum of electronics, ie. RF systems (HF, VHF, UHF, SHF up to 5 GHz), RF Power amplifiers (up to 5 kW), digital systems and embedded systems (SMB for industrial electronics), access control systems, marine electronics (BNWAS), telecommunication systems (GSM/GPRS units), SMPS modules, Power inverters, and too many other that it will take too much space to write them all here.

Chief electronic engineer

FLASH SA
thg 11 2002 - thg 3 2007 (4 năm, 4 tháng)
During the November of 2002 Intracom SA sold the Radio & Television support department to FLASH SA, owner of the FLASH 961 radio station and at that time also for the MAGIC TV station. As a chief engineer of the related department I was directly hired by FLASH SA to keep supporting the stations they owned.

Chief Electronic Engineer
