• Recently I had started my open-source contribution journey. For now it is few issues and 1 merged pull request (bugfix) on GitHub popular open-source projects, but I keep going in this direction ;)

• Thankfully to Python background, I am strong adherent of readable, maintainable and well structured modular code (PEP8, PEP20). Following best practices of languages and technologies I use is priority #1.

Back-end: 
• Python+Django 
• Ruby+Rails 
• Node.js+Sails 
• PostgreSQL 
• MongoDB

• I really like CoffeeScript
• CommonJS (browserify) / AMD (RequireJS)
• Grunt / Gulp
• JQuery
• AngularJS
• ReactJS + Reflux + JSData 
• HTML5+CSS3+Bootstrap/Purecss+Sass/Less+OrganicCSS 

Common stuff:
• Test-driven development
• Linux

Perfect - interesting, complex project with Python on back-end and ReactJS on front-end, and, of course, something new to push into my technology stack :)

But not be afraid to contact me if you are not perfect employer with another technology stack ;)

Also I really excited about React Native, so jump in to fresh project using it will be just a pleasure.
