Kaminsky was a 23rd century Human individual, a crewperson in the Federation's Starfleet in the 2280s decade. Kaminsky was assigned to the weapons division aboard the starship Enterprise-A in the year 2286. As a weapons officer trainee, Kaminsky was under the command of the security chief and tactical officer, Pavel Chekov. During training, a yellow alert caused Chekov to suspend a training session and assign Kaminsky to back up officers in main engineering, where the training group had been attending Chekov's lecture.
