Right now, the field has decided that the coder-designers are worth their weight in gold. As such, at this moment and for the foreseeable future, you are in a great position to pretty much write your own ticket wherever you want to go in the startup world. This will occur even if you don't ever progress your craft beyond being 'very good' at both design and front-end development. For this reason, you now have a good opportunity to decide for yourself what you will enjoy doing most without having to worry about pigeonholing yourself into some particular job description. Also, consider this: if you have become 'very good' at design and 'very good' at coding in 5-6 years of applied practice, then how much further will you push your skill with another 5 years of dedicated effort?
