Stuck as a solo dev

Hello, I've been working at my current job for a little over a year (my first job after graduation) at a small company where I'm the only dev, and I've got a non-technical manager. The first year went okay and I did get to work on some interesting projects which of course I had full ownership. But now I'm feeling stuck, there's really nowhere for me to progress here, and of course I want to learn from seniors and work in projects as a group, so I've been applying the past few months and so far have not received a single interview. I was just wondering wether my current position looks good or bad in a resume. I feel like the more I spend here the more it will hurt my career.
