Hi there, I would consider myself in the same position as you. I have found that if you are not natively from design, I look for inspiration on either websites or apps related to the project. When building an interface I tend to use a Monochromatic (only using one colour). There is a good book that I have started reading called Design for Hackers, which is was written exactly for Developers that have no design experience. If you have any other questions please feel free to contact me.
