Position: Backend разработчик (php, golang)
Category: PHP
English level: intermediate
Years of experience: 11

I created an architecture design using a PostgreSQL extension called “postgres_fdw” and a project written in Go and React, which allowed getting a report with different kinds of data, for example, when it’s needed to know how many of each content was added by each user. 
I wrote the script in Go using goroutines to send push notifications to 40 million devices for 2 hours.
Using the existing e2e tests in the project, we wrote a new service of adding pictures in Go that successfully and
without interruptions replaced in a production environment the existing one, which was written on PHP with the
outdated architecture design and DB structure.
I change the architecture design of the messenger project written by another department, which allowed me to
write unit tests.
I created a React project to send push notifications for internal use.
In 2GIS we have more than 30 microservices (Reviews, Photos, Messenger, Favorite, Auth, Push notification, etc). Almost all projects are written in Golang, but also we have projects written in Yii, Laravel, and Symfony frameworks.

Flamp is review service and was written in Yii1.
I'm looking for a position in the backend team with PHP or Golang languages. I like the Symfony framework.
