Extensive experience on web development and in past in call-centre application management . I started web developing using PHP and its Codeigniter, Kohana, Yii frameworks. For last 5 years I worked as Ruby on rails developer in retail software, delivery services and CRM solution for fitness centers networks. Have an expirience of team leading. Most interesting tasks were optimizing all bottlenecks in project, updating elasticsearch from 3 to 5 version, elasticsearch tuning for auto defining the context of query, typo correction and layout correction; integration with mailing system, with online cachboxes services, implementing API contract tests using rswag gem which compiles then to json for swagger, dockerizing some internal services.

Ruby on Rails, Ruby, Git, MVC, ElasticSearch, Sidekiq, PostgreSQL, Docker, Golang, MongoDB, MySQL

First of all, I'm very proud of my team leading experience, because men can learn anything. But working wth people is another science. Seems like not everything depends on scientific knowledge. I'm also proud of architecture of project where i have been on team lead role. We drived almost 2 years without any architecture issues.

First reason of job searching is that i'am not satisfied of my current duty. I want something more than API bugfixes and API development. I expect more interesting and various tasks. I look forward to be heard expressing my opinion. I expect stable payout of salary.
