I work as a Software Developer at a small company. About a month ago I had a conversation with the VP about a issue one of our largest customers is having. Without any orders I took it upon myself to create a mobile app demo to solve this problem for the customer. After great approval I spent about two weeks creating a excellent polished mobile app for the customer with great approval rate with the VP, President, and the customer's higher ups. Now a deal has not yet been made with the customer but I am wondering what the professional opinion would be about talking to the VP about getting something such as a raise, position bump, etc? Any advice on what to do? Anything would be much appreciated.
Edit: Primarily a position change to something with more responsibility.
