andrzej kała / front-end developer

Passionate Front-end developer for over a decade by day,

An avid gamer by night.

Work experience

In my 10+ years of experience I've been creating websites and web applications using HTML(5), CSS(3) and JavaScript/TypeScript.

I had the opportunity to work with multiple javascript frameworks and libraries over the past few years like Vanilla JS, Lodash, Handlebars, AngularJS, VueJS and lately Angular 6 to name some.

SASS? SCSS? I'm up for it. CSS Transitions? CSS Animations? Check. Same applies to cross-browser compatibility and Responsive Web Design.
