Infourok is the biggest educational online service in Russia, almost all school teachers in the country are registered users (2m+ registered users). What I've done: – refactored a billing module in a legacy project – implemented a new way to buy educational materials – clients are able to buy academic hours and spend it on any course later or send hours as a gift to colleagues. That increased cash flow by 8%. – created a prototype of messenger for project users – created a prototype of social network for teachers with a personalized feed – created and implemented subscriptions system – leaded a small cross-functional team Show less

Helped a popular e-shop with availability and performance issues. Shop is selling merchandise of top bloggers and artists. I've designed cloud infrastructure with backups and scaling, made up Gitlab CI to deploy code, have optimised most problematic peaces of code. I've set up a monitoring panel with Prometheus and Grafana, Also I've dockerized the application.
