Why choose Ruby on Rails for your project?

Fast time to market
Rails was designed for speed - from built-in generators to convention over configuration. You can go from idea to MVP in weeks, not months.
Battle-tested for web apps
From startups to global platforms, Rails has proven itself in production across industries like fintech, e-commerce, education, SaaS, and marketplaces.
Rich ecosystem of gems and tools
Thousands of open-source libraries (gems) save time and reduce boilerplate. Need authentication, file uploads, payments, APIs? There’s likely a well-maintained gem for that.
Clean, maintainable code
Rails encourages readable, well-structured code. Combined with good practices, it enables fast onboarding for new devs and easier long-term maintenance.
Strong community and long-term support
Rails is actively maintained and evolves with the needs of modern web development. The community is mature, helpful, and full of experienced contributors and tooling.

What we deliver

Feature development & product support

Need to accelerate your roadmap? We deliver high-quality features, ask the right questions, and care deeply about user value. We don’t just code - we collaborate to make your product better.

Real full-stack support: backend, frontend, DevOps, and architecture

You don’t need multiple vendors. We handle everything:

  • Backend development (Rails, APIs, background jobs, performance, security)
  • Frontend development (Hotwire, Stimulus, React)
  • DevOps (CI/CD pipelines, hosting, observability, scaling)
  • Architecture (modular design, DDD, boundaries that evolve with your product)

You get a complete, experienced team that understands the full lifecycle of a modern web application.

Scalable architecture & domain modeling

We help design scalable, domain-aligned Rails applications. Whether you need DDD principles, service objects, or CQRS patterns - we bring clarity and structure where it’s needed most.

Performance tuning & database optimization

We make your app faster and more responsive by fixing bottlenecks, improving queries, adding indexes, and reducing memory usage. Real performance improvements backed by metrics - not just gut feeling.

Refactoring and legacy code improvements

We specialize in reviving old Rails codebases. That means refactoring large models, cleaning up controllers, modularizing code, and improving overall maintainability - without rewriting everything from scratch.

Ruby & Rails version upgrades

Running on outdated Ruby or Rails versions? We manage upgrades with care, even in complex codebases with little to no test coverage. We keep your app stable while we move it forward in small, testable steps.

Mentoring and team support

We work alongside your developers, pair on tough problems, and help teams improve their Rails skills. Our background in teaching and content creation makes us ideal partners for growing in-house teams.

How we collaborate

We blend into your team, work in your tools, and keep you fully in the loop - without adding overhead.
You’ll hear from us every day. We share what we did, what we’re working on, and what’s next. You’ll always know where things stand - no micromanagement required.
We focus on the most important tasks first, split them into small, shippable parts, and aim to deliver to production daily. From day one, we write real code and ship real value - not just set up environments.
We adapt to your way of working, not the other way around. Over time, if we see opportunities to improve your code or processes, we’ll suggest them - always with context, examples, and clear reasoning.
We won’t disappear after a few months. Many of our clients work with us for years. We treat your project like it’s our own.

Who we work with

We’ve worked with startups, scaleups, and enterprise teams across Europe and the US. Whether you’re a non-technical founder building an MVP, or a product owner responsible for a growing platform - we adapt to your context.

Some clients come to us for a few months to solve a specific challenge. Others stay for years. In both cases, we act like part of the team - not just an external vendor.

Frequently asked questions

Do I need technical knowledge to work with you?
Not at all. We’ve worked directly with non-technical founders, COOs, product managers, and domain experts. We’ll translate tech into business terms - and make sure you always understand what’s going on.
Can we start small?
Absolutely. Many of our long-term collaborations started with a small upgrade or refactor. We can start with a specific goal or code audit, and build from there.
Do you work with in-house teams?
Yes. In many projects, we work alongside existing developers - contributing code, supporting architecture decisions, and mentoring less experienced team members.
How do you charge for your services?
We typically work on a time & materials basis, billed monthly. No long-term lock-ins, no surprises.
What if our codebase is messy?
We’ve seen worse. We follow a simple rule: leave the code better than we found it. Small improvements, every time we touch it.
Are your developers senior?
Yes - our team is made up of experienced Rails developers only. We don’t hire juniors. You get people who’ve worked on complex apps for 10+ years.
