I will build a ruby on rails API or web application


Over deze dienst
Need a Rails developer who understands production systems, not just tutorials?
I specialize in building Ruby on Rails applications REST APIs, SaaS backends, internal tools, and full-stack web apps. Clean architecture, solid test coverage with RSpec, and code that scales. I've shipped Rails apps handling real traffic across B2B SaaS, fintech, and e-commerce.
What I work with: Ruby on Rails 7+, PostgreSQL, Redis, Sidekiq, RSpec, Hotwire / Turbo, ActiveAdmin, Devise, Pundit, AWS (S3, EC2, RDS), Docker
What you get:
- RESTful or GraphQL API built to standard conventions
- Background job processing (Sidekiq) where needed
- Auth system (Devise / JWT / OAuth)
- RSpec test suite with model, request, and service specs
- Deployment-ready code (Heroku, Render, or AWS)
Whether you need a greenfield Rails app, API-only backend for a React frontend, or help with an existing codebase message me first with your scope.

Veelgestelde vragen
Can you build an API-only Rails backend for my React/Vue frontend?
Yes, this is a common setup I do regularly. I use Rails in API mode with JWT auth and proper CORS configuration.
Do you write tests?
Always. I write RSpec specs covering models, service objects, and request specs as standard. Test coverage is not optional for me.
Can you help with an existing Rails codebase?
Yes. Send me a description of the issue or a brief code review request. Legacy Rails upgrades, performance issues, and architecture improvements are all in scope.
Do you use Hotwire / Turbo?
Yes, for Rails-native frontends. If you want a reactive UI without a JS framework, Hotwire is an excellent choice and I'm comfortable with it.
What databases do you work with?
Primarily PostgreSQL. I also work with Redis for caching and Sidekiq queues. Can integrate with external data sources and third-party
