I will fix bugs, upgrade, and optimize your ruby on rails app
Mehboob R
About this gig
Is a stubborn bug, a failed deploy or an outdated Rails version holding your app back? I find the root cause, fix your Ruby on Rails app properly and explain what changed, so the problem stays fixed.
I'm a full stack Rails + React developer with 5+ years of hands-on experience.
What I fix and improve:
- Bugs, errors and crashes in Rails apps (Rails + React too)
- Rails and Ruby version upgrades (e.g. Rails 5/6 to 7 or 8)
- Slow pages: N+1 queries, missing indexes, caching
- Sidekiq/Redis background job failures
- Broken Stripe payments, webhooks and API integrations
- Failed deployments on Heroku, Render or AWS
- Failing or missing RSpec tests
How it works:
- Send me the error logs or steps to reproduce
- I review your repo and confirm the scope before starting
- I fix, test and push to a branch or pull request
- You get a short report of the cause and the fix
Not included: rebuilding the whole app, new design work or hosting costs.
Message me your error or repo details before ordering and I'll confirm the right package.

Full-Stack Developer with 7+ years building and scaling production web and mobile apps. I specialize in Ruby on Rails, React, Next.js and Flutter, and spent 5+ years as a core engineer on a live US healthcare SaaS platform (prescription care management) where security and uptime were non-negotiable.
Whether you're launching an MVP, refactoring a legacy Rails app, or shipping a cross-platform mobile app, I write clean, maintainable code, communicate clearly, and deliver on time.
Message me before ordering so I can scope your project properly.

FAQ
Do you work with existing repositories?
Yes! I can easily pull down your existing repository from GitHub, GitLab, or Bitbucket, set up the environment locally, and start working immediately.
Can you deploy my Rails app to Render or Heroku?
Absolutely. I can handle the complete deployment pipeline, configure your production database (PostgreSQL/MySQL), set up your master keys/environment variables, and connect your custom domain.
Do you write tests for the features you build?
Yes, I can write unit and integration tests using RSpec or Minitest depending on your current application setup to ensure long-term stability.
Which Rails and Ruby versions do you work with?
I work with legacy and modern apps, from Rails 4/5 up to the latest Rails 8. For upgrades, I move one version at a time and run your tests at each step to avoid surprises.
What if the bug is bigger than my package?
I review your issue before starting. If it needs more work than the package covers, I will explain why and send a custom offer, so you never pay for surprises.
