About DeltaBreen

A small team of engineers in Gorey, Co. Wexford, working with businesses in Ireland and worldwide.

We build and fix software, give independent technical advice, and run our own products. The engineers who scope the work are the same engineers who build, run and support it, so there are no junior handoffs, sales layers or account managers in between.

Who we help

We work with businesses that depend on their software: growing companies that need a system built properly, founders whose app was built with AI tools and now needs cleaning up, organisations with systems that need rescue, and boards or investors who need an independent opinion before a decision, whether that is a cloud migration, technical due diligence or part-time technical leadership.

Our engineering principles

  • Practitioner-ledYou work directly with experienced engineers who have built, scaled and supported production systems for years.
  • Honest scopingIf we are not the right fit for a problem, we say so and, where we can, point you to someone who is.
  • Client independenceEvery project ends with documentation, automated tests and a hands-on handover, so your team can run it without us.
  • Secure by defaultSecrets encrypted, access kept to the minimum, and dependencies scanned and patched from the first commit, not bolted on before launch.
  • Boring, resilient technologyWell-understood, battle-tested tools over unproven hype. Systems should run quietly, predictably and economically.
  • Everything reproducibleInfrastructure as code, automated pipelines, deterministic container builds and version-controlled configuration.
