At the beginning, it was Katch.


In the life of every software engineer, there’s a time in which you have to face a monster. These monsters can be of different kinds, but here I would like to focus on one type in particular: legacy products!


Taking a real example, we’ll go through how my and my team’s personal nightmare, something called Katch, was born, grew and evolved into something similar to a hydra.


And also, how we defeated Katch. And how we’re making sure everything goes well, before its replacement, Skan, will become someone else’s monster.


Because it. Will. Happen.
