Don't think of technical specialty as getting better with tools/processes. Think of technical specialty as getting better at solving classes of problems in a specific domain. Tools come into play and mastering them is a side effect of the problem space. For example, I specialize in the Search domain. Most of all it involves understanding why people can't find things in most search applications, and how to fix them given myriad situations. There is a vast set of skills and tools needed to solve these problems, and I picked them up along the way in the past ~10 years I've been working on it.
