👋🏼 Hi, my name is Jordan. I'm a software engineer based in Vancouver, BC.

This site contains a portfolio of my work and writing. To get in touch, scroll down.


🌊Flow • Oct 2019Now

Flow is a fast, secure, and developer-friendly blockchain built to support the next generation of games, apps, and digital assets. It pioneered many breakthroughs in decentralized technology, including:

  • Separating consensus from compute to achieve high performance without compromising global state atomicity.
  • Cadence, the most ergonomic and safe-by-default programming language available for smart contract development.
  • Accounts with error-resistant addresses, built-in smart contracts, and multi-sig.

I have worked on Flow through 3 code-names and 4 years, starting in 2019. Some of my notable contributions are the Jolteon consensus algorithm, the distributed key generation protocol, the Collection Node, and the automated node operator selection system.

🐈CryptoKitties • Jul 2017Sep 2018

CryptoKitties is the world's furriest blockchain experience. It defined the standard for non-fungible tokens, coined the term "NFT", and accidentally broke Ethereum when it launched.

I prototyped the product with the initial team of 4, launched the alpha at the inaugural ETHWaterloo hackathon, and developed the smart contracts, among other things. CrypoKitties has been covered in the BBC, New York Times, Wall Street Journal, and many others.

Alongside Flow's consensus team, I spent nearly a year researching, designing, and implementing an upgrade to Flow's core consensus algorithm. The upgrade decreased finality time by about 30% and enabled automated recovery from DOS attacks, networking outages, and partitions. In addition to a summary of technical changes, my goal with this article is to provide a high-level intuition for how and why the HotStuff family of consensus algorithms work.
