Build a GUI for filtering stocks and a set of fields
Sardar once again shows how quickly he can complete a request in record time. I have nothing but praise for his professionalism and skill in completing a task. In addition he gave me documentation on the use of the GUI and patiently went over how to use it. Extremely easy to work with.
