First of all, sorry to hear you’re not getting any responses. I can sympathize with that and it sucks. Unfortunately it is pretty typical in this industry even for experienced devs.
For what it’s worth, looking at your portfolio I stopped at DogBase and already knew you were job-ready.
Seeing that your last commit was over 12 months ago on that project and assuming that you’ve been continuing to learn and build over the last 12 months I would be very confident hiring you as a junior dev if I were in the position to do so.
I would absolutely take @jwilkins.oboe advice if you haven’t done so already. A more focused approach is much better than just sending hundreds of resumes out.
I’m not sure if those videos mention it, but I would also keep focus on networking. Attend meetups (even virtual ones) and conferences if you can. Get active on socials in dev communities, build and learn in public etc.
Most people I know, including myself, get that first lucky break through someone they know. They either work somewhere that has an opportunity come up and you’re the first person they think of, or they know someone who’s looking for someone and they refer you.
I’m not a professional resume writer so I don’t know how useful my feedback is but overall I think it’s fine. As a developer who’s sometimes involved in the hiring process I usually skim resumes pretty fast anyway and am more interested in seeing projects and code.
Personally, I think your DogBase app is a really good portfolio piece in terms of execution and in terms of a unique product idea. I’d be curious as to why you stopped working on it. I would keep running with it and see how far you can take it. I think if you treat DogBase like a real product that you intend to turn into a profitable side-hustle it would not only boost the heck out of your credentials, it could make you a bit of passive income while you learn too.
If you take DogBase seriously as a product with users that makes money, you can scratch it off your “Personal Projects” section on your resume and add it to your “Work History” and make it front and center.
Hopefully that’s helpful, and good luck!
