- Website makes you look like a front end developer, but you are applying to full stack.
Stepping back a bit, an employer is asking the question: is this person the best person for the job that I'm hiring for? As the job seeker, you need to think about what type of job you are going to be the ideal candidate for and really focus on communicating that.
- Bullet points on resume could be improved. For example, Content is easily added or removed using a JSON configuration file Its a given that you would do that. It is so basic that it raised a flag in my mind. Its like saying, I used numpy to do math computations in python. It would be better to not include that statement.
Full stack web developer who will help your company succeed by completing projects on time and under budget. This sentence comes off as pretty generic, and it is not clear that you have experience with that. It would be better to have an experience where you delivered a project under time constraints.
Anyways, sorry that I'm nitpicking a bit. It is hard to know exactly what is holding you back without knowing more about what jobs you are applying to, what is happening in the interviews, and so on.
I'd also think about if there is any company you can work at where having some background in industrial automation would be a plus.
