I am a founder and blockchain engineer working in crypto since 2017. Currently, I'm researching what to work on next in the DeFi space. I'm most familiar with Solidity and the EVM, while I am also familiar with the Cosmos ecosystem, rust, and typescript. On the research side I am focused on DeFi. I write on Substack and tweet from @davekaj. I occasionally angel invest.

Cycles - 2024 - 2025

Ekonomia & Photon Finance - 2022 - 2023

As a contractor through my corporation, I was hired to build the smart contracts for The Graph Network, which launched in December 2020. I stopped working on The Graph to work on Ekonomia.
