hands. >psi software engineer. i worked for planning systems, inc. as a junior software engineer. i mainly developed software using matlab. the main project i worked on was a matlab gui that was used for post processing of submarine tracking data. i designed, coded, and tested the entire package myself and got to use it on a submarine trial out in the bahamas aboard a naval acoustic research vessel. it was a good job and i enjoyed the work and adventure in working on the submarine trials, but left psi for an opportunity in a smaller company designing hardware and getting away from programming. for more information, visit http://www.plansys.com
