Help me build Swift infrastructure for web and legal

I see a future where no person again faces the unjust reality that economic differences significantly dictate legal outcomes. To reach that future, we need technology that makes legal services accessible and affordable.

Another reality is that the infrastructure to reach this, just isn't there yet.

That's why I build type-safe Swift web infrastructure—from PostgreSQL queries to HTML rendering, from payments to email. 90+ open source packages working together in production. Pioneering server-side Swift through real-world systems that prove the language's potential beyond iOS.

And I plan to take all my learnings back to legal.

Philosophy

Start from the bottom-up. Compose onto that foundation. Use maths and algebra where no-one else is. The general solution, even if it requires more up front work, will emerge. Test. Embrace the human factor.

My question to you

I've dedicated my professional life to deliver on a vision so many share: that technology should improve justice for all. And it's a thrill seeing years of work come together, at this very moment, that will deliver on that promise.

If you like what I build, support my goals, or whatever your reason may be, I promise you this: your sponsorship is valued and will be put to good use. Let's do this together.
