Our production Rails app (PostgreSQL-backed) needs steady, hands-on care. I’d like you to jump straight into the existing repository, clean up the bugs users are currently reporting, then move on to building out a handful of new public-facing web pages we have specced. Both the frontend and backend require attention: some views are mis-rendering, controller logic is throwing sporadic errors, and a few queries are clearly under-optimized. You’ll be free to refactor where it makes sense, as long as test coverage remains solid and deployment to our Heroku pipeline stays smooth. Key deliverables • Closed tickets for all reported bugs, with clear commit messages referencing each issue ID • Fully implemented new pages (HAML/ERB, Stimulus, SCSS) wired to existing models and controllers • Any necessary migrations or schema tweaks to keep the database consistent, plus performance improvements where slow queries are identified • Passing RSpec suite and green checks in our GitHub Actions workflow You’ll be working in a standard Rails 7 stack—PostgreSQL, Sidekiq, Redis, Hotwire/Turbo—with Git for version control. I review pull requests daily and can provide quick feedback, so you’ll never be blocked for long. If you’re comfortable tackling bugs first and shipping features right after, let’s get started.

Hi, I’m happy to step straight into your existing Rails 7 application and prioritise the current production issues before moving on to the new public-facing pages. I’ll begin by reproducing and resolving the reported bugs, refactoring where necessary while maintaining solid test coverage and ensuring the RSpec suite and GitHub Actions pipeline remain green. Any performance concerns—particularly around PostgreSQL queries—will be reviewed and optimised appropriately. Once stability is restored, I’ll implement the new pages (HAML/ERB, Stimulus, SCSS), cleanly integrated with your existing models and controllers. Any required migrations will be handled carefully to maintain data integrity and smooth Heroku deployments. I’m comfortable across Rails 7, PostgreSQL, Sidekiq, Redis, Hotwire/Turbo, and structured Git workflows. I provide clear commit messages tied to ticket IDs and keep pull requests focused and easy to review. If that aligns with what you’re after, I’m ready to get started.

Hi, As per my understanding: You need an experienced Rails developer to immediately stabilize your production Rails 7 app (PostgreSQL-backed), resolve active user-reported bugs across views, controllers, and queries, and then implement new public-facing pages. Refactoring is allowed where beneficial, provided test coverage remains solid and Heroku deployments continue smoothly via your GitHub Actions pipeline. Implementation approach: I will begin with a focused bug audit: reproducing issues, reviewing logs, profiling slow PostgreSQL queries, and validating controller/view logic. Fixes will be delivered via structured PRs with clear commit references to ticket IDs. I’ll optimize queries (indexes, eager loading, N+1 fixes), refactor safely, and maintain RSpec coverage. For new pages, I’ll implement HAML/ERB views styled with SCSS and wired through existing models/controllers using Hotwire/Stimulus where needed. Any schema changes will include clean migrations and rollback safety. All updates will pass RSpec and CI before merge and Heroku deployment. A few quick questions: Approximate number of open bug tickets? Any known performance bottlenecks already identified? Is staging mirrored to production data? Expected timeline for new page rollout?

Hi There Hope this message finds you well! We have strong hands-on expertise in Ruby on Rails (Rails 6/7) and production-grade PostgreSQL applications, and we’re very comfortable stepping directly into an existing codebase to stabilize, refactor, and enhance it without disrupting live operations. From your description, this is exactly the kind of engagement we have past experience and specialize in — fixing production issues first, then delivering cleanly implemented new features. In this kind of level we generally follow below approach (1) Stable existing things (2) Enhancement (UI/UX + Feature) If you’re looking for a team that can immediately take ownership of bugs and then move straight into structured feature delivery — we’re ready to start. Looking forward to collaborating. Best regards
