Project Wikidi.com
I was working on wikidi.com during my first 5 months. The software compares various attributes of products which helps users with their buying decisions. The project has become successful and it was crucial to focus on scalability and performance of the entire project. It was a first time in my life when I wrote tests for my code.

Project Flowreader.com
After I finished the Wikidi project, I have become a full-time JavaScript developer on flowreader.com. We have built the project from scratch and I was in charge of the decision about technology we would use on a frontend because it was a single page application. The decision was Google Closure. The benefits were static analysis of the code (type checking) and compiler which squeeze the application into 40kb. When the application got bigger we added ReactJS in order to improve scalability. Rendering components became much easier to develop or debug. Great times!
