Profile

My technological stack mainly consist of open source technologies and cloud services. I am a javascript supporter for NodeJS and web frameworks (e.g Angular/Js, React, Backbone) but comfortable with more traditional languages (e.g PHP, Python). I write SCSS or use CSS frameworks like TailwindCSS, Bootstrap to speed up styling of my projects.

Software Engineer with 10+ years experience in several IT-areas. Main directions of development are frontend and backend stack development. Skilled at algorithms and data structures. Good communication skills. Excellent team player.

Being result-driven person I am always working towards updating my professional skills and believe it's possible mix up the business and pleasure.
