Double Up with Test Double at Rails World Meet us in the Double Up Lab

Our consultants partner with developers at clients like GitHub and Gusto to solve hard problems and have fun doing it. We want to share that experience with everyone!

Join us in the Double Up Lab in the Sponsor Lounge to pair and write some Rails. Bring something to work on or pop by to recharge and chat. We also offer no-strings-attached career & resume pairing.

Some things people bring us:

Hard Rails problems — the bug you can't shake, the weird edge case, the thing that's been nagging at you
Legacy system struggles — old codebases, tricky upgrades, modularizing a monolith that's grown past what one team can hold in their head
Working with AI the right way — using AI tools without letting your tests, deploys, and architecture fall behind
Resume review and career chats — get an outside perspective from someone doing the job

You'll get 30 minutes with one of our senior consultants, matched to what you're working on.

Last year filled up quickly, so grab a spot now. If we're full, you can join the waitlist or book a virtual session after the conference.
