Our experience in working with legacy systems

We have split old monolithic systems into manageable pieces. As a result, we have turned old ‘dinosaurs’ into the cloud-native approach, microservices, and event-based architecture. We have done it for multimillion-dollar international corporations based in the USA, the UK, and Nordic Europe. We’ve also helped new technology companies that quickly accumulate legacy systems in-house.

What we can do for companies battling their legacy software


If you want to build a new and shiny front-end but are worried about the underlying back-end systems, there is no need to rebuild the whole infrastructure. We can build new applications on top of existing ones, exposing ancient systems in a modern and appealing way to your customers.

Your financial savings will be significant: faster time to production, downtime minimized, improved reaction time to defects.

We build development pipelines that improve the maintainability and reliability of the solutions regardless of who maintains them.

Solutions we offer:

  • Maintenance of older legacy software systems
  • Moving monolithic systems to the cloud
  • Remodeling parts of a legacy system that need to be transformed
  • Infrastructure for building modern applications (mobile or web apps)
Project
Result
We took over a code base written 15 years ago and modernized it to the latest tech stack for a global taxation consultancy company.
System deployments are now pushed to production instantly, instead of once a quarter, allowing continuous introduction of any new services for the business.
We took over an older large project for a regional tech company building a P2P marketplace for businesses and turned it around technically.
The project went live within 3 months, instead of previously planned 1.5 years. The team of 4 people was used, instead of an inefficient group of 9.
We extracted an invoicing module from a legacy system for a large Northern European insurance company and integrated it with the ERP.
Enabled system releases every day instead of once every 2-3 months. Zero downtime deployments instead of risky releases during evenings and weekends.
