Work Experience

Self-employed
- Developed PinupWarlords, a blockchain-based play-to-win game on WAX, encompassing smart contracts, back end, front end, and a Unity-based game.
- Built a non-fungible token (NFT) marketplace over six months, working with the team behind Scatter, the most popular EOSIO wallet. Also worked on tools for EOSIO integration into Unity (C#) and JavaScript.
- Audited the C++ smart contracts for Kyber Network's EOS port, an on-chain liquidity network similar to Bancor.
- Created a tool on Solana for generating provable randomness, useful for any contracts that deal with chance.
- Constructed a cross-chain tool to send tokens from one EOSIO-based chain to another.
- Developed smart contracts for pixEOS, a pixel master-based game for the EOS blockchain.
- Created the LiquidApps Zeus SDK package manager, allowing Zeus boxes to be versioned and packaged similarly to npm modules, simplifying the use of LiquidApps' VRAM technology, and making EOSIO smart contracts significantly cheaper to deploy.

Experience
Infiniverse
https://www.youtube.com/watch?v=hpvY85pPGqEDue to the scarcity of real-world space, users must purchase or rent “land,” the digital layer of real-world locations, in order to place persistent content there. Infiniverse has its own economy and virtual currency, Infinicoin, which is used to register land and make transactions on the marketplace.
I led the project vision, technology architecture, partnerships, funding, and operations. While the project was ultimately put on hold due to a lack of funds, I am proud of our achievements, including being selected to pitch onstage at AWE 2018 and for collaboration and partnership with Samsung Next.
