I help SaaS teams fix, scale, and modernize Ruby on Rails products with proof: $200K+ earned, 7,600+ Upwork hours, 100% Job Success, and 5,000+ hours on one long-term SaaS platform. Invite me when you need Rails performance, API work, backend architecture, or legacy Rails cleanup. Problems I Solve - Slow Rails apps caused by database, query, or architecture bottlenecks - SaaS products that outgrew their MVP codebase - Legacy Rails systems that are hard to maintain, test, or extend - APIs and integrations that need to be reliable in production How I Help I design, build, and refactor Ruby on Rails applications with clean backend architecture, practical testing, and production-grade delivery. My work is focused on maintainability, performance, and systems that stay easy to improve as the product grows. Core Services - Ruby on Rails backend and full-stack development - SaaS architecture, MVP-to-scale refactoring, and technical debt reduction - REST API development and third-party integrations - PostgreSQL/MySQL performance tuning and data modeling - RSpec/TDD test coverage and code quality improvements - React/Next.js interfaces connected to Rails backends - Cloud deployment and production support on AWS/GCP Tech Focus Ruby on Rails, Ruby, PostgreSQL, MySQL, RSpec, Capybara, JavaScript, TypeScript, React, Next.js, AWS, GCP, Nginx, Puma, Capistrano, Mina, Heroku. Clients usually bring me in when they need a senior Rails engineer who can understand the product, improve the system, and keep shipping without adding brittle code.
