A senior Rails team you can outsource to
FusionHit is where US teams outsource Ruby on Rails without the cost and lead time of hiring in-house. Senior nearshore engineers, fluent in modern Rails, Hotwire, and ActiveRecord performance tuning, work in your time zone as an extension of your team.
\ Ruby on Rails services we provide
One senior team across the full Rails lifecycle, from a new build to a rescue.
Custom Rails application development
Products built the Rails way, so the next team can read them without a tour.
Rails version upgrades
Rails 4, 5, and 6 apps brought to a supported release, one version at a time.
Rails rescue and code audit
Inherited apps with no docs and no tests, mapped and stabilized before any feature work.
API and headless Rails development
Rails as a clean backend for a separate front end or mobile client.
Performance and database tuning
N+1 queries, missing indexes, and backed-up job queues, fixed against real p95 numbers.
DevOps and Heroku exit
Moves to AWS or Kamal when the platform bill outgrows the convenience.

Flexible engagement
Scale your Rails team up or down as your roadmap and priorities move.
