I will build a rails backend, rest API or graphql API for your web or mobile app


MuhammadHamza
About this gig
Need a backend your front-end team can rely on? I build API-only Ruby on Rails backends with REST or GraphQL. I'm a senior Rails engineer with eight years on production web apps and SaaS platforms.
WHAT I CAN BUILD
- REST or GraphQL endpoints shaped around what your front end needs
- Authentication, including single sign-on (SSO)
- PostgreSQL or MySQL database design
- Multi-tenant setups for SaaS products
- RSpec or Minitest tests for the endpoints
- Written documentation of the API for your front-end developers
ALSO AVAILABLE
- New endpoints added to an existing Rails API
- Fixes for endpoints that fail
- Bug fixes and new features in existing Rails apps
- Rails version upgrades
- Payment endpoints with Stripe or PayPal
HOW IT WORKS
- Message me with what the API needs to do and who will use it.
- I confirm scope, price and delivery time before you order.
- You receive the code with tests, documentation and setup notes.
Please message me before ordering so I can confirm the details.

Senior Ruby on Rails engineer with eight years in production Rails. I build systems that handle money and keep working when the internet doesn't: payment integrations (Stripe with 3D Secure, PayPal, Amazon Pay, Apple Pay, Google Pay), multi-tenant SaaS and API-only backends on PostgreSQL or MySQL. I'm the founder and sole engineer of Hajza, a booking and point-of-sale platform live with paying venues in Pakistan and the UAE, and a Senior Backend Engineer on restaurant reservation software. Every change ships with tests. Message me before ordering and I'll confirm scope, price and delivery.
