The mystery is solved!
Hello all, my name is Diederik, a Dutch race engineer for MP Motorsport living in Kyiv - and in 2018 I ran the car #31 with Renault F1 Academy star Christian Lundgaard in the Formula Renault championship

I once asked my lovely Ukrainian wife Julia Gitaristka to buy me something to put my papers in, she did and that's how I started with my Sprava folders ? We got to be rookie champion and 2nd place overall, so they are good folders!!
Anyway, I am part of this group now so I am available for any questions regarding racing. Obviously I travel a lot for my work, but also in Ukraine a lot so who knows, maybe see you around!

Thanks to Vyacheslav Potapenko for informing my team, they loved it and thanks to my friend Oleg Boiko for pointing me to all the mystery that was unfolding here ?
