For OmbuLabs · Software Engineer Contractor (Ruby on Rails)

Joel Gaff, Jr.

Rails developer, available for contract or full-time work. Remote, from Portland, Oregon.

OmbuLabs helps clients with Rails upgrades, feature work, and maintenance. I've spent four-plus years building and maintaining my own production Rails apps, and the newest run on Rails 8.

Why I'm a fit for OmbuLabs' Software Engineer Contractor (Ruby on Rails)

Here's what the posting asks for, and what I've actually done.

Ruby, Rails, Git, JavaScript
Four-plus years of Ruby on Rails across nearly a dozen production apps. Partita Doppia, Grateful Deploy, and Home HQ run on Rails 8 with Hotwire, and I've written a TypeScript phone web app.
Writing simple, clear code that is easy to maintain
I build in the 37signals style on purpose: one Rails monolith, Hotwire, and SQLite. Fewer moving parts means less to maintain.
Maintenance and keeping apps healthy
I maintain every app I've shipped myself, including migrations, DNS, and deploys, and I built Grateful Deploy to see each app's version, health, and memory and roll back with a button.
Testing
Partita Doppia and Grateful Deploy ship with Minitest suites (model, integration, and system tests) and a pre-push hook.
Code reviews on pull requests
I've had pull requests reviewed and merged into Omarchy, omarchy-time-machine, and omacaffeine.
Communicating with and demoing work to clients
I co-host The Pingback Podcast with Greg Molnar, talking about Rails and indie products, and I write at joelgaff.com.
Capable of making important decisions, both detail-oriented and practical
As a manager of one I make every product and technical call on my apps, and execute without supervision.
Remote
I'm in Portland, Oregon, on Pacific Time.

To be upfront: I write tests with Minitest rather than RSpec, and I deploy with Kamal rather than Heroku.

About

I'm a self-taught Ruby on Rails developer in Portland, Oregon. Over the past four-plus years I've designed, built, and run nearly a dozen production Rails apps, solo. I handle every migration, the DNS records, and the deploys.

I borrow a lot from 37signals: a single Rails monolith, Hotwire on the front end, and almost always SQLite. I deploy with Kamal, including to my own home server through a Cloudflare tunnel.

I'm looking for a full-time full stack or backend role, open to remote or Portland, Oregon.

I'll be at SF Ruby, Nov 10-11, 2026. If you're there too, come say hi.

Most relevant work
