About
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.
Available for
Freelance consulting on offline-first PWAs, Web Crypto / client-side encryption, and trauma-informed product design. Open to collaborations and sponsorships around PainTracker.ca and privacy-respecting health tech. If you’re shipping health tech or developer tools and want an offline-first, trauma-informed review, reach out via X or Hashnode DMs. PainTracker.ca is the reference implementation behind CrisisCore’s Protective Computing work: local-first software designed for users under pain, stress, instability, and low-trust conditions.
