During my time at MARA, I was part of a software innovation team where we developed a variety of MVPS/Softwares, one of which was Avant.
Avant was a RWA platform, that allowed crypto holders to invest in real-world assets including things like Whiskey, Gold, Mining Farms etc. Tricky part was to also make sure we have a loaning platform in-built so people didn't have to use actual dollars and could use their crypto wallet to get real world return.
This project was a couple of weeks of work, and I did the end to end design.
