Services / Application Software Development

Software built around how your business actually works.

We design and build web, mobile and hybrid applications, and we modernize older systems so they are easier to change. Our own products are built by the same team.

What we cover

Hybrid Applications

One application for the browser, the phone and the desk

Customers, field staff and back-office teams need the same information in different places. We build hybrid applications that share one code base and one back end across web and mobile, so new features reach everyone at once.

More on Hybrid application development →

What we do

  • Customer portals and staff workspaces
  • Mobile companion apps
  • Role-based access for every type of user
  • Low-code where it is enough, custom code where it is not

Application Modernization

From one large system to parts you can change safely

Monolithic applications get slow to change because every update touches everything. We split them into smaller services with clear interfaces, one piece at a time, so the business keeps running on the old system while the new one grows around it.

What we do

  • Architecture review and modernization roadmap
  • Monolith to microservices, step by step
  • APIs around legacy functions
  • Automated testing before every release
