Major (first and until recently biggest) on-line social network service in Poland. I was hired as a JavaScript guru to clean up a mess and set standards for future client-side code development in this high scale environment.

Starting with multiple JS frameworks, libraries and a messy, unstandardized, spaghetti code, after overwhelming amount of work we ended up with consistent library with solid API and good documentation. We have standardized work flow across company and developed internal set of guidelines about coding style and good practices.
