I&#x27;m a full stack developer. Although not an expert in all areas, I&#x27;m efficient and productive in almost all of the areas listed.<p>Then again, I&#x27;m creeping on 40 and thus, slowly getting fewer and fewer recruiter calls. This is definitely an industry that prioritizes youth (i.e. low expense) over execution, experience, skills, and breadth of knowledge.<p>But, also, I&#x27;m probably only in the top 10% (sampling over the over 200 developers that I&#x27;ve worked with). And, I&#x27;ve worked with a few exceptional people who would destroy me, in overall comparison.
