Our Services

Clearing technical debt

If you’re encountering bugs from outdated systems or projects overrunning, it’s time to perform some maintenance.

We’ve worked on everything from old Rails 2.3 software to legacy apps running with no test coverage and broken Node.js dependencies.

We can give your codebase a refresh, with tasks such as:

  • Framework updates
  • Increasing test coverage
  • Repository workflows
  • Untangling spaghetti code
  • Technical documentation
  • Code readability
  • Adopting Agile processes
  • Dependency updates
  • Refactor to modular architecture

We also run a subsidiary company,, that specializes in version upgrades for Ruby on Rails.

Software Development

We’re experienced at developing new capabilities for existing software or new apps to add to a company’s product line.

Every project is tackled with the latest technologies and best practices. We use an Agile approach to solve real business problems with as little code as possible.

We can work on the projects you need expert help with, such as:

  • Frontend Features
  • API updates
  • Tie-in applications
  • New integrations
  • Cross-platform development
  • Building MVPs
  • Design Sprints
  • Security improvements
  • UX/UI improvements

Why Choose OmbuLabs?

We are a boutique development agency, running since 2011. Since then we have worked on everything from niche tools to Fortune 500s.

Our size means your project will receive a pair of dedicated developers, not a mystery team of people switching in and out. We aim to be an extension of your company, getting up and running ASAP.

And of course, we only want to ship quality code. That’s why every line we write goes through a rigorous QA process of automated tests, code reviews and staging before it goes into production.
