In my case, I have a full-time job unrelated to free software, and I dedicate substantial time outside of work to my free software. You are wrong to assume that a developer who has programming interests outside of work, would somehow fail to give you "full attention" on the job. If anything, it shows that the developer knows how to write many different kinds of programs (a strength).
