  Participating in four big projects.The first is a “Andromeda Online2” – transport monitoring system (GPS, GLONASS). I prepared and made migration from memcache to membase cluster. I wrote scripts for automatic backup (full and incremental) and restore PostgreSQL(8.4) database, and scripts for backup and restore Membase. Also i deployed Sphinx text-search engine. I got experience in writing PostgreSQL stored procedures, found and fixed few "bottlenecks" related to inefficiency database index using. I learned a lot about XML, XSLT and XPath, since on them was based the templating in frontend.The second project, is the “Cloud” – distributed cloud services for security companies. I participated in architecture planning. I implemented message routing system based on RabbitMQ "headers exchanges". Wrote several helpful Erlang applications for Redis clustering. I introduced the usage of AngularJS in frontend development. The third is the “Private Cloud” – boxed version of “Cloud”, which installs on VMware ESX(i) instead of AWS.I prepared the tools for data migration from DynamoDB to PostgreSQL(9.3) in "Cloud". The tools was written in Elixir. I planned and performed migration procedure.The fourth project is the "Hubble" – desktop software for configuration security devices. Used technologies: Python, Qt, WebKit, AngularJS.Since february 2017 Angular2 (4+) is used for all new web-interfaces.From 2019 working on new Video Monitoring project. Stack: golang, postgresql 12, grpc on backend and ReactJS on frontend.
