I have experience with e-commerce platforms. I was developing scoutandnimble.com - online store based on Spree Commerce framework. I was responsible for front-end side (JS, jQuery), and back-end side (RoR, Spree Commerce, simple scrappers in Nightmare.js). I have also developed a video on demand platform for fishermen - Hooka.tv. The platform was developed with Vimeo API - I have implemented my authorization proprietary solutions to prevent unauthorized access to videos. I had a pleasure to work on getAuto.pl (now carQ.pl) - platform to generate reports about your car history. I've worked side-by-side with a graphic designer to improve UX, but also I was participating in the optimization of platform speed and creating new features. I can also work with SPA framework, not only jQuery. Vue.JS is my new passion. Besides writing web applications, I also develop Ruby gems.
