Senior Ruby on Rails Engineer · Rails Modernization Specialist
I take Rails applications that have fallen behind and bring them forward one version at a time, without pausing feature work. 10+ years of production Rails: upgrades from as far back as Rails 2, multi-tenant architecture, background jobs and memory work. Contributor to Ruby on Rails and to the upgrade tooling the community relies on.

A few weeks ago I looked at my dotfiles AI configuration and realized I’d over-engineered it. What started as a clean centralization effort had grown into a web of submodules, global MCP servers, a...
Why HAML in the First Place When I started building the clinical assistance app, HAML felt like a breath of fresh air. No closing tags. No angle brackets everywhere. Just clean, indentation-based ...
The Original Setup When I started this Rails app back in 2018, Sprockets was the only game in town. It bundled your JavaScript, compiled your CSS, fingerprinted assets for cache busting — and you ...
Rails 7.2 shipped native PWA scaffolding: a manifest.json.erb and a service-worker.js under app/views/pwa/. Two files, two routes, and your Rails app is installable. But one piece was still missing...
The Starting Point The Doctors app — is a multi-tenant Rails 8.1 application. Each clinic gets its own subdomain: demo.doctors.com, drasmith.doctors.com, and so on. File storage goes to Cloudflare...
The Timeline I started the Doctors app — the clinical assistance system I’ve been writing about recently — in October 2018 on Rails 5.2.1 with Ruby 2.5.1. Today it runs Rails 8.1 on Ruby 3.4.8. Th...
Last weekend I migrated my Doctors App from Heroku to Railway. It’s a multi-tenant Rails app where each hospital gets its own subdomain — one.doctors.com, two.doctors.com, and so on. Five hospita...
