During the 18 years of Shalom's computer work, he took active part in development of communications systems, including LAN and WAN development, commercial client server database systems, CAD software and security software, at all levels. Shalom also spent time as a system manager and a network manager for a community of over 2000 people spread over five continents.

Before attaining his degree as a software engineer from the University of Southern Maine, Shalom was a merchant marine electrical engineer. In this capacity he was in charge of power generations in the megawatt range, power distribution and automatic control systems and he worked closely with navigation and other shipboard equipment. Combining the experience he gained with his hobby as a ham radio operator, Shalom created many electronic and control designs. Those range from industrial measurement and control systems to a number of embedded systems.

Besides his professional work, Shalom is also an inventor. His extensive marine and underwater experience drove him to invent and patent a sonar based ship navigation system. His interest in aviation drove him to develop inventions in this field. Shalom also developed other inventions and tools in the areas of electronics, machining and carpentry.  Shalom is now pursuing another venture - manufacturing and marketing one of his inventions -  the Staticoff Zapper Stopper, which is a simple lightswitch coverplate that prevents electrostatic shcok.

As a US registered patent agent certified to practice in the United States Patent and Trademark Office (Registration No. 43,359), Shalom currently dedicates most of his time to Saltamar Innovations and its clients. Like many of us, he wishes he had some more time for his inventions and hobbies.
