Development of a highly-secured blockchain asset token management platform.

Developing and maintaining a website with a large code base https://foreverstudios.com and its Russian version (currently inactive). I redesigned the English version of the site (backend) for the Russian market, added a payment system via Yookassa, configured servers for dev and production environments with automatic deployment from a self-hosted gitlab server to yandex cloud (compute cloud with docker containers, nginx as reverse proxy and letsencrypt for certificates, Object Storage as file storage). Developed a marketing system with automatic sending of emails to users with different order compositions, different emails at different time intervals and an email constructor (handlebars as a template engine). Developed the integration of the English version of the site with Stripe, Twilio (incoming/outgoing SMS and calls), and set up integration with Freshsales.Developed a system of internal testing for students/employees for universities and other educational institutions with tests, blogs, emails, analytics and statistics for different time periods/groups of students or employees, an internal messenger using websockets to send and receive messages in real time.The projects were developed using Node.js (TypeScript), PostgreSQL, Knex and NestJS (Express)

Development of the video streaming/news/reviews platform using such technologies as Nest.js, Postgres, MiniO as video/audio storage, Angular and ffmpeg, was also responsible for SRE and DevOps.
