as a teleco and IT expert
I have worked in computing and telecomputing (hardware and software) since the heyday of CP/M, MS-DOS and BBSs (In the 80s I ran a
popular BBS called Polyglot from my office in Udagawa-cho, Shibuya.). Later on I installed Netware servers and peer-to-peer LANs.
As a Telecom engineer at NEC, where I worked for 11 years until March 2005, I acquired a wide knowledge of transmission technologies
Network Management Systems; and
GSM/GPRS, WAP, 3G mobile terminals and network as well.
I also work with Sun Solaris, Linux, Cisco routers, other networking gear. I know well the whole Microsoft Windows platform, including hardware, OSs and applications.
