I clean your Rails codebase
with specialized coding agents.
You probably don't need another developer. You need a specialized fleet of AI agents that upgrade, test, and refactor your codebase while your team focuses on shipping features.
The age of AI slop is dead. We can now be productive on large and old codebases with clear architectural direction.
Why am I qualified?
I'm Damian. I've spent 15 years inside large Rails codebases. I've been coding since 2005. My first open source contribution was in October 2010. My first public repo was a Perl HTTP API in February 2012. This is just in case you think I'm a 20 years old kid playing with AI: I'm not.
Trust me: I've seen the same pattern destroy velocity at company after company. Teams hire brilliant developers to build features, but the "janitorial work" (upgrades, flaky tests, refactoring) gets ignored until it kills momentum.
Here's what nobody tells you: hiring more humans to fix technical debt is a losing battle. It's slow, it's expensive, and your best developers hate doing it.
I only use standard solutions: Claude Code, OpenCode with OpenRouter. Nothing proprietary.
Sound familiar?
These problems are solved. It just takes the right process and the right tools.
The "Friday Fear"
You only deploy once a day. Never on Fridays. Your CI takes 45 minutes and you don't trust the test suite. Every merge feels like rolling the dice.
The Upgrade Wall
You're stuck on Rails 6.0. You know you need to upgrade to 7.2 or 8.2. But it's a massive project nobody wants to own. This doesn't have to be painful.
The Never-ending Roadmap
The product team is waiting for features to ship. But features get more and more expensive to build because of legacy code. The backlog just keeps growing.
The AI Illusion
You gave your team Cursor and Copilot. Great tools. But here's what happened: they write legacy code faster now. The architecture problems? Still there. The right agents change this.
You won't get there in a week. You first need to clean your codebase while training your engineers. The better your codebase, the better the coding agents are going to be productive. You can get there in 4 to 8 weeks.
How Each Agent Works
Transparency builds trust. I'll show you exactly what each agent does, its safety guarantees, and what to expect. No black boxes.
Gem Upgrade Agent
Automated dependency upgrades with changelog analysis, CVE detection, and isolated test validation.
Code Review Agent
Deep review for security vulnerabilities, N+1 queries, architecture drift, and Rails best practices.
Rails Version Upgrader
Major Rails version migrations (6 to 7 to 8) with zeitwerk fixes and config updates. Done.
Legacy Code Refactor
Extract god objects, split fat controllers, modernize patterns. The scary code becomes maintainable.
Test Fixer Agent
Diagnose and fix failing and flaky RSpec tests. From red CI to deterministic green. No more re-running.
Performance Fixer Agent
Fix N+1 queries, add missing indexes, optimize memory. Your app gets faster without hours of profiling.
Auto Doc Agent
Generate YARD comments, READMEs, and API docs from code analysis. Always up to date.
New Feature Planner Agent
Plan implementations with architecture decisions and task breakdown. Clarity, not guesswork.
I18n Extractor Agent
Extract hardcoded strings to locale files. Going global becomes a lot less painful.
Fast Boot Optimizer Agent
Reduce Rails boot time by optimizing gem loading and initialization. Seconds, not minutes.
Harmonise Views Agent
Standardize spacing, colors, and styling across views. One product, not a patchwork.
Fix Linter Agent
Resolve RuboCop, ESLint, and style violations automatically. Clean code without the tedium.
Works Well With Your Stack
My agents adapt to your existing infrastructure. No migration required, no vendor lock-in. They work with what you already have.
Something's not listed here? Don't worry. Just tell me and we can train an agent for your specific tech stack.
The Future of Development
Internalize Your Agents
You need to own your automation. Use the latest models. Customize the workflows. Keep your code private. Agents become permanent assets that stay with your company forever. This is how you future-proof your stack.
Redefine Developer Roles
Your developers shouldn't spend 80% of their time on execution and 20% on strategy. Flip that ratio. Let AI handle the grunt work while your team focuses on product vision and meaningful innovation.
The future is you writing clean product specifications and validating results with code review, QA instructions, and reports.
How I Differ From Agencies
| Capability | Me | Typical Agencies |
|---|---|---|
| Custom AI Agents (not SaaS) | ✓ | ✗ |
| Codebase stays private | ✓ | Partial |
| 15 years Rails expertise | ✓ | Partial |
| Agents evolve with your code | ✓ | ✗ |
| Direct access to expert | ✓ | Team |
Questions You Might Have
"We have a unique stack. Will this work?"
Let me be direct: yes. The agents learn your specific patterns. I build them to understand your codebase's unique architecture. They adapt to you, not the other way around.
"We tried Cursor/Copilot and the code was garbage."
That was 4 months ago. Models have evolved dramatically. But more importantly, bad results usually come from poor context, not bad models. My agents add context intelligently. They understand your codebase before they write a single line.
"Do we implement all agents at once?"
Absolutely not. We start step-by-step, targeting your biggest bottleneck first. Monitor results. Then add more agents as needed. No overwhelm. Just steady progress.
"Do you push to production?"
No. Every change on your codebase is a dedicated branch and pull request. Nothing gets merged without a human in the loop from your team.
"Can we do everything remotely?"
Yes. All collaboration happens via Slack, GitHub, and video calls. I work with companies worldwide. Distance doesn't slow anything down.
How We Work Together
I work on projects from 4 to 8 weeks, depending on your team organization and codebase.
Full engagement for 4 to 8 weeks
The ROI is simple.
A typical engagement frees up $200k+ / year in senior engineering time. How? By removing the recurring friction that slows everyone down: slow CI, upgrade debt, risky refactors. Your team stops firefighting and starts building.
This also improves Revenue Per Employee by increasing output without increasing headcount. Your CFO will notice.
Let's turn your Rails app into a masterpiece.
You're closer than you think to cleaning all your legacy code.
