Where can a student go for an internship?

Question

IT education

Hello comrades. I am a student at St. Petersburg in my second year.
For a year at the university I was coding in C++, but then,
about 8 months ago, I began to study HTML, CSS on my own, and a few months later I took up JS.
Now I have basic knowledge of HTML5, CSS3 - semantics, adaptability, and native JS, I understand DOM and AJAX quite well. English at a good level.
Recently, familiar programmers suggested that different companies hire students in the process of obtaining their education.
Can someone suggest similar offices in St. Petersburg? I want to do my favorite and useful thing, and not work as a waiter, albeit for a slightly higher salary, besides, I want to gain experience (I really like web development), now I'm focused on working in the front-end.
Alas, in my financial situation, I just need a job besides studying.
