Rails codebase audit & sprint

Damian Le NouailleRuby on Rails

Get your Rails team moving again.

Slow CI. Flaky tests. Upgrades that keep slipping. I tackle the maintenance backlog while your team keeps building the product.

I'm Damian, a senior engineer with 15 years of Rails experience. You work directly with me, from the first diagnosis to the final handover.

The work that never makes the roadmap.

Your team knows it matters. Product deadlines keep winning.

  1. Slow, unreliable CI

    Shorter feedback loops. Fewer flaky tests. Checks your team can trust.

  2. Postponed upgrades

    A staged path through Ruby, Rails and gem upgrades, with compatibility checks.

  3. Code that slows every change

    Focused refactoring and performance fixes, protected by regression tests.

  4. An inconsistent UI

    Coherent components and smoother user journeys across the product.

Find the bottleneck.
Then clear it.

Start with an audit if the priorities are unclear. Go straight to a scoped sprint if you already know what needs fixing.

Discuss a sprint

Fixed scope and acceptance criteria agreed before kickoff.

Progress you can see.
Changes you can review.

I use coding agents to accelerate the work. I own the architecture, review the code, and validate each change before it reaches your team.

  1. 01

    Agree what success means

    Pick the priorities, record the baseline, and define acceptance criteria with your technical lead.

  2. 02

    Keep reviews manageable

    A shared delivery hub brings together the plan, PRs, test evidence and daily status. Your team controls approvals and merges.

  3. 03

    Leave a stronger codebase

    Compare results with the baseline. Hand over the changes, documentation and next priorities.

Before we talk.

We already use coding agents. Why bring you in?

Your team can keep using its tools. I bring dedicated ownership of the maintenance backlog, production Rails experience, and the time to carry changes through validation and review.

How much time does my team need to give you?

One technical contact, a kickoff, a weekly check-in, and regular PR review. We agree a realistic review budget before committing to the scope.

What access do you need?

Repository access, CI results and a safe test environment. We agree permissions and AI tooling with you before starting. Production access is only requested when the agreed work requires it.

Can we work together from North America?

Yes. I'm based in Madrid and can arrange three to four hours of overlap with US Eastern time. I speak English, French and Spanish.

What's slowing your Rails team down?

Bring your biggest bottleneck. In 15 minutes, we'll see whether an audit or a sprint makes sense.
