Avant arte's NFT platform

https://avantarte.com/story/nfts
I acted as a lead developer for Avant Arte, building their NFT platform. It's not my personal project but an accumulation of teamwork, where I took a leading role within the NFT space.

Avant Arte is a marketplace for art. Some of it is physical, like their eCommerce store, but some is digital, and that is where the NFT sales come from.

Within a year, our NFT sales reached one million dollars, facilitated by the smart contracts that I mostly wrote and in a platform that I was the leading developer in, making decisions around the architecture and development of it, with more to come.
