Hi, thanks for the intro @Karolina JunÄytÄ!
Actually, I did the migration on my own, that's why I titled the talk "one woman show" :) that's what I basically wanted to show the audience, that with a good & well-thought of plan and structuring the project, you can pull off something big as full on migration on your own (other teams took care of some aspects, but the heavy lifting was on my side)
And this project took place on one of my previous companies :)
