Rails apps, rescued or built right.

Upgrades for Rails and Ruby of any age, and MVPs that hold up in production. Expert hands on your code, start to finish.

How we work

No surprises, by design

Every engagement starts small and bounded, so you see the work before you commit to more.

  1. Step 1

    Assess

    A fixed-fee, capped look at where things stand: risks, quick wins, and an honest call on fit.

  2. Step 2

    Plan

    A sequenced roadmap with ranges, not guesses. You know what comes first and why.

  3. Step 3

    Build and maintain

    Prepaid monthly capacity pointed at the roadmap, with regular check-ins and reports.

Work

Proof, not promises

Idea to production

Designed, built, and shipped products from first commit to production deploy, infrastructure included.

Every Rails, every Ruby

Rescued and upgraded production apps across the full range of Rails and Ruby versions, oldest to newest.

Millions of lines

Shipped features and major upgrades inside codebases with millions of lines of code.

Why Ferrum

Built like a good weld: clean, strong, no shortcuts

A senior engineer, directly

You work with the person doing the work, not an account manager.

Honest fit calls

If you don't need custom software, we'll tell you.

The right tool for the job

Rails for applications, static sites for brochures. Never more stack than you need.

AI-assisted, human-reviewed

We use AI tools to move faster. A person reviews every change, and the contract says so.

Is your site slow on a phone?

We'll run a free speed check and send you a one-page report: what visitors wait for, and why.

FAQ

Common questions

Do you publish prices?

Yes. Every service page lists its pricing options, so you know the range before we talk.

Why prepaid?

It keeps scope clear and both sides honest. You pay for a defined piece of work or a month of capacity, and you always know what you are getting.

Do you host websites?

We can host static sites for a flat monthly fee, or set everything up in your own accounts and hand you the keys. Your choice.

Do you use AI?

Yes, as a tool. A person reviews every change before it ships, and our contracts disclose how AI is used.

Assessments usually start within [X] days. Larger work is scheduled from the assessment.
