No offense but if your boss thought of, designed and delegated to you a project, then he did build it. Most programmers on HN are competent enough to put together a project based on specs, that’s kinda baseline to be considered a programmer.
If you identified an opportunity, presented it to him, drove the process of getting it prioritized and built it, then you deserve credit and he should 100% be mentioning you.
