Bernecky's first published APL work concerned with speeding up the iota and epsilon (index-of and membership) primitives functions by orders of magnitude.[2] While at IPSA, he was a colleague of Roger Hui,[3] Dick Lathwell,[4] Eugene McDonnell,[5] Roger Moore, Arthur Whitney, and APL inventor Ken Iverson.[5][6] He continued on after IPSA was acquired by Reuters on 1987-04-01, and left Reuters in 1990 to found Snake Island Research. He works on APL compiler and parallel-processing technology to this day.

Bernecky holds the Master of Science degree from the University of Toronto.[7]
