About this gig

Need a Ruby on Rails backend that is built for real production use, not just a quick demo?

I develop clean, scalable REST APIs and backend features using Ruby on Rails, PostgreSQL, Redis, and Sidekiq. My experience includes working on a production Rails platform spanning 370+ API routes and building custom CRM, AI automation, and business workflow systems.

I can help with:


  • REST API development
  • Bug fixing
  • Existing Rails application development
  • PostgreSQL database design
  • JWT authentication and authorization
  • Role-based access control (RBAC)
  • Sidekiq and Redis background jobs
  • Webhooks and third-party API integrations
  • Meta Lead Ads integration
  • Email, SMTP, and email API integrations
  • Portal and external platform integrations
  • Lead capture and automated lead routing
  • WebSockets and real-time features
  • File uploads and cloud storage
  • Deployment and production configuration


I can also connect your backend with external services so that Meta ad leads, website inquiries, emails, portals, and other lead sources flow directly into your CRM or application.

My focus is clean architecture, reliable integrations, secure APIs, and maintainable production code.
