Objective swiss army knife
Marcin Haręza 
JDD 2021 Current project is old, tech leader even older and design was lost? Don't wait for another greenfield project, code cleaner and in a more objective way right here,right now. I will demonstrate a few ready to use techniques/recipes/patterns that will make your code better, more readable and, what is most important, more satisfying. Demonstrated techniques will be objective design oriented and will fit in almost every codebase no matter how old, neglected, complex and tangled.
