Every single one of my jobs came not from networking, but just cold applying to positions. If networking feels inauthentic to you, I would say just to forget about it and work at getting good at your craft. If you can demonstrate you have the skills and a company has a need for that skillset, they will hire and networking skills will be irrelevant.
Also, if you're not having much success at applying for a type of position, it may be that the timing is just not right, e.g. a company has a superabundance of web developers, but what they are really in need of is embedded software developers. In a lot of cases, it's not about you, but about what the company's needs are.
At one point in time, I applied to a company and failed to get in, but later on, I tried again, got the position, and it was a great opportunity. Was I that much better? Not really, just a timing thing.
So don't give up and keep moving forward with practicing your skills and applying. The more you prepare and try, the better the odds of success.
