“Based dev, good friend”

“Makes the best smart contracts”Comes up with the weirdest unintelligible solutions to reducing gas, to the point where I can't actually read the code anymore because it's so optimised.

“Friendly and crack dev!”First came across Francis from the sappy seal community but didn't know him that well, just on TL. I also didn't know he has worked with Sappy Seals helping with dev work. I finally met him on a call and impressed with his work on an App he is a founder of. Definately worth a follow if you need some crack smart contracts. Francis is a great developer building gamified dApps and the like and is the founder of Hashcrash

“Great dev”Francis has been helping Pons on the dev side of things quite often and has also recently released his new game hashcrash on abstract. One if not the best odds for a gambling application. Appreciate his work.

“Badass Builder”Francis is an amazing friend, skilled developer, and super knowledgeable builder in the space! Over the years, I have seen many amazing things built by Francis (pun intended). Lots of high-powered teams put a lot of trust into him, which speaks volumes. Even I was able to do some work with them recently, helping him test one of his new apps. Extremely glad to have crossed their path.
