Building Technical Sophistication As A Developer Idea and concept wise it’s something we all developers are quite aware of. I first came through this exact term, “technical sophistication” in Michael Hartl’s article in Learn Enough Society. The basic idea is as developer one requires a certain set of skills which can elevate their overall vision and can see things in a broad sight. One need not be technically proficient at everything but having good understanding of fundamentals enables us to debug and reach the solution faster.
