Freelance

Web3 Developer & Advisor (Nov 2022 - Now)

For the last two years, I have been working full time as a freelance developer and advisor in crypto and NFTs. I have been finding clients, advising on technology and infrastructure, developing custom solutions, and teaching others. It has been incredibly fulfilling getting to learn from and meet people from around the globe. It has also given me a chance to create personal projects, some of which can be found in my portfolio.

Some of my key accomplishments include helping teams to raise a combined $3,000,000+ through the creation and sale of their NFT collections, developing and maintaining staking solutions responsible for $5,000,000+ of assets, and teaching dozens of developers how to get started with developing in web3.
