Looking for a project just like yours. I have been working in Web3.0 and crypto since 2019. I have been a freelance developer since 2008. I am a full-time digital nomad and would really like to find a solid project to work on. I am focused on blockchain and web3.0. I spend nearly 3 hours a day learning as much as I can. I am a senior developer, consultant, and problem solver. The tools to do that will always change. While I can say I have 7 years of Solidity development, I can say I have over 30 years experience solving issues with technology. If you are interested in working with someone like me I would like to connect and see if we are a good match. Regards, Phillip Williams
