I started to learn programming in PHP and MySQL about 8 years ago. A litte after that i learned how to program in OOP way. With that i started also learning (front-end) Javascript. I worked with native JS and jQuery. About the beginning of 2012 a friend of mine suggested to try Node.js. I thought why not since syntax was already familiar. I realized that i could write async and/or sync, depending of need. Since then i've used Node.js as main server-side web application. At this time i also started to learn PostgreSQL and SQLite. Within last few years i've worked with some FE libraries like Sencha Ext.JS 4.x,5.x (MVC) and Webix. So far i've built software for production, warehouse and logicstics.
