The math on a full-time hire doesn't work anymore

Same senior talent, none of the search, ramp, or long-term risk.

Hiring full-time
  • Months to hire. Sourcing, screening, and offers while your roadmap slips every sprint.
  • Weeks to ramp. Even a strong hire needs time to get productive in your codebase.
  • A bad hire is costly. Salary, benefits, and a setback that's hard to undo.
  • Fixed capacity. Hard to scale up for a push or down when priorities change.
A FastRuby.io engineer
  • Starts next week. Vetted senior engineers, ready to embed. No search required.
  • Productive from day one. Parachuting into unfamiliar codebases is our core skill after 14+ years.
  • Debt-aware by default. A decade of cleanup means they ship fast without creating expensive rewrites.
  • Flexible capacity. Add review bandwidth or delivery muscle, scale as priorities change.

From backlog to shipping in three steps

Step 01

Tell us what you're shipping

Share your roadmap and stack. We scope the fit in a single call. No long sales cycle.

Step 02

We embed a vetted engineer

They adopt your tools, process, and standards from day one. AI-native, with a trusted human in the loop.

Step 03

Ship from week one

You set priorities, we add the capacity to hit them: stories picked up, bugs fixed, features shipped.

Extra code-review capacity

AI writes code faster than teams can review it. Our seniors take a share of the review load: correctness, security, maintainability.

Debt-aware by default

The best way to reduce technical debt is to never write it. A decade of cleanup gives us an eye for shortcuts that become rewrites.

Measurable outcomes, not vague praise.

Upgraded our legacy app to Rails 8.1 and Ruby 3.4 on time and on budget. They went beyond expectations and made the transition invisible to our users.
Tomasz Matyjasik Director of Engineering, Epassi
Very on the ball, asking good questions, high attention to detail. 10/10. I'd have no reservations recommending this service, especially to early-stage startups.
Nathan Broadbent Founder, DocSpring
They exceeded our expectations, went above and beyond, and worked with the junior developer on our team to get to full productivity.
Will Bridges Director of Engineering, Storenvy

A fantastic addition to the team, and we're thrilled to see Rails 4.0 booting. We would definitely come back to FastRuby.io for staff augmentation.

Chris Warren, Director of Engineering, Arux

Tell us what you're shipping this year.

A short conversation is enough to tell whether we're a fit. Even if staff augmentation isn't perfect for you yet, we're happy to point you in the right direction.
