How to go from simple working code to professional code

[whcirobotics]

Hi I was the programmer for team 1514 last year and we did pretty well. Our robot had autonomous which worked 90% of the times and claw and everything worked but the code was "simple". Simple in the sense that it had a bunch of if statements and such, but it did not have any "professional infrastructure". I was wondering if any experienced Labview programmer might know how to make that transition of making simple code to sophisticated professional code. The coding I do works great, but it looks like a bunch of if statements and you get the point. Any help would be appreciated. Tnx
