You don't need a portfolio to get a web dev job. Just show them you are able to code. Try to get a front end developer job if you prefer that to backend. You can learn to integrate Photoshop templates while on the job without problem.
Show them you can learn and you're a good coder. I don't think they'll ask for a portfolio, you're not a web designer.
