The work in this position began with the tasks of fixing bugs and developing new functionality on two sites that were written on Yii many years ago. After six months of such tasks, the management made a decision to move one of the sites (and later the second one) to Wordpress. The whole backend, frontend - everything was done by me on my own. Also, one of the priority tasks was the optimization of sites for Google Page Speed, and this task is still a priority when developing all kinds of projects, so we are constantly working on it. Both sites are highload projects. Both have a multi-node structure - Nginx + multiple php nodes + mysql nodes. Due to the frequent absence of contractors DevOps to work with this structure, I have to edit configs from time to time, fix some problems. One of the next big tasks was restoring a site from scratch after a fire in OVH from Google cache (writing a parser and all the logic). After that - site was moved from old framework to Wordpress and new multi-node structure. On one of the sites, a user's personal account was developed from scratch, with a subscription to newspapers, a premium account, and all sorts of bonuses. Since a fairly large part of site monetization is advertising, there is a lot of experience working with it, I also wrote my own js library for ad optimization in order to multiply the performance. A multilingual version was also deployed on all sites of the holding. There were a lot of optimization issues because of this.At the moment, writing an application for the holding site on Flutter.

Worked as a support in the TV industry (German Internet TV company). The main devices that were used were Android TV boxes. In addition to supporting the set-top boxes themselves, we partially had to fix bugs on them.

In 2011-2014, while studying at the university, worked as a full-stack developer. The tech stack was PHP / JS / C# / C++. Plus administration.
