My production application is still running on an older version of Ruby on Rails and all three layers—user interface, backend, and database—now need to be brought up to the latest stable release. User interface The HTML/CSS and front-end Rails helpers must be refactored so every view renders correctly after the framework jump. This includes replacing any deprecated helpers, updating the asset pipeline (or moving to import-maps/webpacker as appropriate), and making sure responsiveness remains intact across modern browsers. Backend functionality I want the entire codebase upgraded to the newest Rails and Ruby versions. That means adjusting initializers, gems, and configuration files, removing deprecated methods, and making sure all tests pass. Performance tweaks and bug fixes that naturally arise from the upgrade should be handled along the way. Database Run and verify all required migrations, update [login to view URL], and resolve any adapter changes. I use PostgreSQL in production, so please ensure compatibility and zero data loss. Deliverables • A clean, passing test suite (RSpec) on the upgraded versions • Updated Gemfile, lock file, and documentation of major changes • Database migration scripts with rollback instructions • A concise upgrade report outlining what was changed and any follow-up tasks Code lives on a private GitHub repo; work through PRs so I can review each step. Continuous deployment is wired to Heroku, so the final merge should trigger a successful pipeline build. If you have recent, provable experience taking Rails apps through multi-version jumps, let’s get started right away.

Hello, I hope you’re well. I’ve helped Rails apps navigate multi-version upgrades end-to-end as a solo developer, from planning to production validation. I’m comfortable with the full stack, Rails, Ruby, PostgreSQL, CSS/JS, asset pipelines, and CI/CD on Heroku, tackling upgrade blockers and ensuring compatibility across UI, backend, and database layers. I’ve delivered successful Rails upgrades by refactoring deprecated helpers, upgrading gems, updating initializers, and validating with a robust test suite (RSpec). I’ll upgrade the codebase to the latest stable Rails/Ruby, adjust configuration, migrate assets, run migrations, update schema, and verify zero data loss with PostgreSQL. I’ll keep the Gemfile/lockfile in sync, document major changes, and provide migration scripts with rollback steps. The PR-based workflow will let you review changes step by step, and the pipeline will trigger a clean Heroku build on merge. I can handle the work end-to-end based on my experience and past upgrades. You’ll get a concise upgrade report and reliable test coverage delivering a robust, modern app. Please feel free to contact me so we can discuss more details. I am looking forward to the chance of working together. Best regards, Billy Bryan

Hey there, What Rails and Ruby versions are you upgrading from, and is the app still on Sprockets, Webpacker, or a mixed asset setup right now? Also, do you want the upgrade done as one controlled version jump plan through PRs, or as staged upgrades so each step stays easier to review and deploy on Heroku? For a Rails upgrade like this, the real work is managing gem compatibility, deprecated helpers, config changes, asset pipeline updates, and PostgreSQL safety without breaking production behavior. I can take the app through a clean multi-version upgrade path, fix views and helpers, update initializers and gems, run and verify migrations, and get the RSpec suite passing on the target Ruby and Rails versions. I will keep everything PR-based, document major changes clearly, and make sure the final merge is ready for a successful Heroku pipeline build. Looking forward to discussing more on chat. Best, Kostiantyn
