  Work on web-application development direction.Backend stack include such technologies like: 1) PostgreSQL (ORM + native SQL/plpgsql) - create complex logic not only on backend server side, but right in database with plplsql procedures, 2) Ruby ( + Ruby on Rails) - work on modification Instructure Canvas LMS and build some private applications. 3) Python ( + Django/Django CMS) - build learning system where business logic moved on database layer (to increase perfomance), also build task tracker based on React.js in frontend and REST services in backend structure. In frontend I have experience with: 1) jQuery - create simple async statefull components. 2) Backbone.js - create component to represent dynamic tree structure with abillity to create/delete/update nodes. 3) React.js - (with state control by Redux). Create one-page application to manage some kind of tasks. Also use Router to build complex sitemap without page reloading. 4) CSS/Sass/Scss - create mixtures and functions to effective styles organize. 5) Bootstrap 4 - fast developing of page layouts.Creating unit tests for every project. Try to use TDD methodology.All projects are under version control: Git, Mercurial. Show less
