Sometimes I love over engineering my projects. It helps me hone my skills and keep updated. But I limit my self to one side. E.g. Back end or front end.

In my case, it's back end. API and stuffs. I'm also trying to limit my self in using different kinds of language. My current Back end stuff today are Grails for web app, Scala for non web, Redis, memcached, MongoDB.

Don't ask me about front end. I'm not updated with it by choice.
