Building privacy first health tools that fail safely when users are already under pressure.

I’m the founder of CrisisCore Systems and the developer behind PainTracker.ca, a privacy-first, offline-first pain journal built for people who’ve been failed by “normal” health apps. I build PWAs that run entirely on your device, use real encryption, and respect trauma and crisis instead of exploiting them. Here I write about Web Crypto, IndexedDB, workers’ comp evidence, and building software that still works when life doesn’t.
