Frequently asked questions

How should we plan an upgrade from Rails 7 to Rails 8?

Start by checking Ruby requirements, gem compatibility, and test coverage for critical workflows. Rails 8 requires Ruby 3.2 or newer. Move through appropriate intermediate releases, resolve deprecations, and review framework defaults separately from dependency updates. Exercise authentication, serialized attributes, assets, and background jobs in staging before scheduling the production rollout.

Can a Rails developer improve slow PostgreSQL queries?

Yes, but first identify whether time is spent in database execution, excessive queries, or Ruby object allocation. Use ActiveSupport instrumentation, query logs, and PostgreSQL EXPLAIN ANALYZE where appropriate. Fixes may involve eager loading, better indexes, narrower selects, or pagination. Tools such as Bullet can flag N+1 patterns but do not replace production-representative investigation.

Should our Rails application use Sidekiq or Solid Queue?

Sidekiq uses Redis and has an established operational model for background processing. Solid Queue is database-backed and is the default Active Job backend in Rails 8. Compare throughput requirements, scheduling, database capacity, and existing operations. Either choice still needs idempotent jobs, retry policies, and protection against executing work before its transaction commits.

Is Hotwire a good alternative to a React frontend for Rails?

Hotwire, including Turbo and Stimulus, fits many server-rendered workflows such as forms, account settings, and internal tools. React may suit interfaces with substantial client-side state or rich interaction independent of navigation. Review the actual screens and team maintenance needs. A Rails application can also use targeted React components without replacing its entire view layer.

How do we evaluate a senior US-based Rails developer?

Ask candidates to reason through a risky migration, an N+1 query, and a job that runs twice. Discuss RSpec or Minitest coverage alongside deployment and rollback decisions, not just Rails conventions. Most teams interview matched engineers within a week of the first call. Book a 15-minute call to describe your application and priorities.

Are your developers really based in the US?

Yes. Every engineer lives and works in the United States. No offshore subcontracting and no hand-offs to another team. That's written into the contract.

How fast can someone start?

Most teams interview matched engineers within a week of the first call. Start dates depend on your interview process.
