About this gig

Build a production-ready Ruby on Rails REST or GraphQL API clean code, tested, documented, and ready to deploy.


I'm a senior software engineer with 18+ years of experience. My primary stack is Ruby on Rails + PostgreSQL + GraphQL. I've shipped production APIs for B2B SaaS platforms, ERPs, restaurant tech integrations, fintech platforms, and e-commerce systems.


What you get:

- RESTful or GraphQL API built with Ruby on Rails

- JWT or token-based authentication

- PostgreSQL database with proper migrations

- RSpec test coverage

- Clean, readable, well-structured code

- README with setup and deployment instructions

- Docker-ready configuration (Standard and Premium)


My background:

I've built APIs for Coupa (cloud spend management), Brokrete (B2B ERP with 272+ models), HubRise (restaurant POS integrations), CityFalcon (fintech news), and more. Commercial Rails development since 2007.


Why work with me:

- Code that's easy to maintain and extend

- Clear communication and honest delivery estimates

- I use AI-assisted development tools for faster turnaround without cutting corners
