Gymigo

I completed the back-end part of this project I'd received from previous dev. All business logic run by go (mobile API, websocket interactions when app is in live mode and business logic itself), Django for admin purposes

Saint-Petersburg Library System

http://lermontovka-spb.ru
This is a project I was supporting for some time. Mainly interesting because of search optimization I've made and quick bug-fixing in the project you're not super-familiar by the time you're starting.

Booking System for Students Preparing to Take the Government Exams

http://manager.5iz5.ru
This project consists of three parts: teacher's part (managing students, schedule, attendance's lists etc), student part (profile page with courses and lessons details, teachers contact info etc.), and managers part (control over financial part of the deal, running reports and managing the app).

Saint-Petersburg's Language School project

http://peremena.com.ru
This is the full-stack friendship project I made for the International language school in Saint Petersburg. The project is mostly interesting in back-end (django, django-cms, django-cosial-auth, django-rest-captcha, django-tinymce). I made it fully customizable on the back-end, which led to the current look of the front-end..
