I am a founder and blockchain engineer working in crypto since 2017. On the engineering side I focus on Solidity and the EVM, and I am currently teaching myself Rust. On the research side I focus on DeFi and monetary system designs. I am interested in the holistic design of protocols and how we can build a parallel financial system that is better than the current one. I write on Medium and tweet from @davekaj. I occasionally angel invest.

Currently, I'm looking to collaborate with engineers and researchers on open-source projects. If you are interested in collaborating, please reach out.

Past Work

Some recents posts below:

Ekonomia & Photon Finance - 2022 - 2023

Founder, CEO and CTO. Grew to a team of 9 people. After 1 year we shut it down before launching a product. We moved too slow and did not innovate enough on decentralized stablecoins.

The Graph / Edge and Node - 2018 - 2021

I was the seventh hire on the team, and the first smart contract engineer. We built and launched The Graph Network in late 2020 with a small team. I left in early 2021 to pursue my own projects.

Polymath - 2017-2018 (Now known as Polymesh)

I joined as the second hire on the team as a smart contract engineer and helped contribute to the launch of the network in early 2018. I left to work on The Graph.
