Pet projects:
- Prediction market web-application: a platform, the principle of which is similar to the stock market, only stocks are predictions. Built with Django, REST Framework and Django Channels, PostgreSQL used as a main database.
Frontend is written using React with a state container Redux. To deploy and scale web application on the AWS cloud platform Elastic Beanstalk service was used.
- Streaming platform: a thin streaming platform with chat, user roles and achievements system, different locales support, websocket and REST APIs. Backend is written in Django, RESTFul API with the Django REST Framework and Django Channels for handling websocket connections. Commits from UI repo and tests execution configured using GitHub Actions. Sessions and websocket events use Redis for simplicity and speed increasing. UI built using React with a state container Redux. Video streaming implemented via RTMP server (via nginx).
- code quality;
- coverage of all tasks with tests;
- practice code review;
- desire to use and study new practices and technologies.

Останні 2 роки працюю на позиції Middle Python Engineer. Виконую задачі, що пов'язані з розробкою нового функціоналу для аналітичної платформи та торгової платформи. Також в мої обов'язки входить підтримка інфраструктури kubernetes та розробка архітектурних рішень, для оптимізації роботи системи.
Останні пів року неформально виконую обов'язки team lead, впроваджую кращі практики та підходи для роботи в команді й підвищення якості роботи. Основним фреймворком є Django Rest, проте поступово відмовляюсь від монолітного підходу в сторону мікросервісів, використовуючи фреймворк FastApi та ORM SqlAlchemy.
В попередній компанії проект був в області VoIP, в мої обов'язки входило розробка сервісів що допомагають підтримувати роботу системи, а саме: авторизація, моніторинг, автотести системи, автоматизація розбудови інфраструктури.
Також маю 1.5 роки досвіду в сфері ML та DS. Розробляв систему моніторингу падінь людей похилого віку в лікарні. На основі мережі семантичної сегментації людей було натреновано нейромережу для класифікації падінь людини. Іншим проектом був сервіс заміни рекламних банерів у кадрі, потрібно було виявлати потенційні місця вставки рекламних банерів та вставляти туди рекламу максимально нативно.
Також мав фріланс досвід з реалізацією search engine на основі ElasticSearch.
Прагну розвиватись одночасно в управлінському та інженерному напрямку.
Маю ступінь магістра з комп'ютерних наук.
