Refactoring and more with GDG3City

• 6:00 PM: Big Refactoring Story - Mikołaj Nowak - Senior Android Developer @ SpotOn

Anyone who has been working in their career with a long-running project has come across some big, old, legacy piece of code that was hard to maintain. While you can often hear complaints about such code, it’s much less common to hear that someone actually managed to refactor it.

Probably the first thing you find challenging is to convince the Business to give you time to do such a rewrite. However, a big refactor brings even more significant challenges you might not initially think of:

• how to make sure you won’t start complaining again about that piece of code after a few months
• how to deliver it in an acceptable amount of time
• how to involve the whole team in work on such refactor
• how not to lose some features implemented in the legacy code
• how not to change the direction of the planned solution during refactoring
• My team managed to get the time and find solutions to all the problems above! I’ll share how we did it from the code and the process perspective. I’ll also give you some tips we worked out during our refactor.
• Spoiler alert: we were surprised how smooth the refactor went for us, so it would rather be a success instead of a trial and error story.

• 6:45 PM: TBD - TBD

We can't tell you yet what exactly, but I promise you it will be great presentation!
