Not unlike many programmers David Karapetyan stumbled into programming while trying to attain a graduate degree in a related technical field. In his case it happened to be mathematics and while he enjoyed the abstractions and mental gymnastics involved in proving theorems at the end of the day opening up a shell and writing a Ruby script to demonstrate an edge case of some theorem was far more satisfying. So after attaining a Masters degree in mathematics he entered the field of software testing and reliability and hasn't looked back. These days his tools for quickly accomplishing a task are C# and PowerShell. He works at eSolar as a Software Test Engineer verifying the proper functionality of software that controls fields of heliostats at a concentrated solar power plant. The complicated nature of the software and its high reliability requirements mean that there must be a lot of automation in the verification and testing process in order to meet tight release deadlines. As the software runs on Windows the right tool for maintaining the testing and automation framework for verifying the software is PowerShell because it integrates seamlessly with all the components that comprise the testing framework.
