Hi! I'm Jeff. I'm technically a biologist (studied photosynthesis, then vegan cheese proteins), but have been mostly coding for a few years now. Here are some of the things I've worked on outside work...

ElectionGuard + Cardano

ElectionGuard + Cardano

Blockchain elections using Microsoft's open source election toolkit. I want to make it easy to run or verify an election without specialized infrastructure, and easy to understand the privacy/security/usability tradeoffs.

BigTrees

BigTrees

Performant hash trees to dedup large collections of files. Like cleaning out your basement for millenials.

Horcrux

Horcrux

Immortality for your backups! Encrypt backups to a public key, gather secret shares to decrypt. Optionally hide secrets in images or audio files.

Crypto Island

cryptoisland.blog

Your standard developer blog. I try to keep it relatively short and full of example code. Sometimes I fail at the short part.
