The product has became very big with 14.000.000 of users accounts. Being part of that I learned a lot about how to develop high scalable applications with thousand of users. I also have worked with the Spring Framework and with Grails in the past. In the freetime, I try to learn new things like AngularJS, do swimming and play soccer.
