I am a professional tech lead architect with more than 5 years of experience working in building large-scale web applications. Have solid experience in using php starting from 4 to 7 versions. Have already built tens of products using best PHP frameworks: Laravel, Symphony 2, Yii framework, Kohana, CodeIgniter, Phalcon framework , CakePHP etc. along with custom php code. Moreover I have wide expertise using both SQL databases (such as MySQL, PostgreSQL, SQLite) and NoSQL databases (MongoDB, Elasticsearch, CouchDB). Have already built multiple products using best JS frameworks: Node.JS, Express.js, Sails.js, AngularJS, React.js, VueJS, Backbone.js., Meteor, TypeScript and etc. I'm also experienced in front-end development using technologies and libraries as follows: HTML5/CSS3, JS-libraries (jQuery, Vanilla JS, Underscore.js etc.). Surely I use CSS preprocessors (Less, Sass, Stylus); front-end frameworks (Bootstrap, Foundation, Google's Material Design), build tools (Gulp, Webpack, Grunt). I am also pretty familiar with deploying and maintenance of applications which use AWS services such as: EC2, Docker, RDS, Load Balancer, S3, Cloudfront, etc. I tend to use Source Control systems like GIT (branches, tags, cherrypicks, rebase) or SVN during my work process. I have extremely good problem solving/trouble-shooting skills and my attention to details is what sets me apart from other developers.
