Why Haystack
The fastest way to hire Ruby on Rails developers - without the agency tax.
Rails is having a moment again - Hotwire, Turbo, view components and a renewed monolith-first ethos. The hire that matters is someone who can both ship features at Rails velocity and reach into ActiveRecord internals when needed.
What they ship
Production Ruby on Rails work, not tutorials.
- Rails 7+ apps with Hotwire and Turbo Frames
- Sidekiq job hierarchies with retry, dead-letter and concurrency control
- Multi-tenant Rails apps with row-level security
- Performance work on slow database queries and view rendering
