- developing VDI service inside wide cloud infrastructure

Leading a team of six developers of different levels in cases of: - developing a service for medical clinics by splitting old monolith into different parts - developing new core system for bunch of clinics integrated with third-part system, storing data about doctors and patients via REST - migrating legacy handmade full-text search system built on top of Python requests module to new instruments - refactoring of old Django template-related code, closely binded to front-end side, to a separate REST API and separate front-end client made with React

Developing different features on backend of distributed cloud computing platform in Python, such as: - adding availability for virtual machines located on nodes of our clusters to communicate with partially available external storage systems - adding availability to use cache for often used components of virtual machines, mostly, disk images - expanding functionality of using stored templates vor virtual machines deploying - expanding the functionality of the system in terms of migrating virtual machines between hosts

Developed server(Python) and client(Android) sides of specific mobile app for blind people to read audiobooks, use web services such as Wikipedia, Yandex.Weather etc.Was engaged in Linux Kernel for Android development by patching audiosystem, WiFi and filesystems drivers for our specific hardware (C, C++)

Developed microservice infrastructure for object recognition platformSuccessfuly migrated MVP of this solution to async architecture which made it possible to speed up the response of the system by 30-50%
