It's more my lack of depth with any of those aside from maybe Laravel that I would feel dishonest calling myself senior. I've made CRUD apps until my eyes bleed, but not a whole lot else. I don't have a lot of experience writing tests. I don't really have any open source code to show employers, only past projects that I've made as a side project or for an employer. It's rare that I have to write anything original that isn't already covered by the existing conventions of whatever framework I'm using.

It just feels like a few years experience isn't "senior" when you look at the candidate market in general. I am probably well below the average numbers of years experience.
