Technology and delivery approach

Project delivery commonly combines native mobile development (Swift, Kotlin), cross-platform Flutter work and cloud-based backends built with Elixir/Phoenix. Deployments use Google Cloud Platform and AWS. The company executes full product lifecycles from concept and UX design through development, testing and app store publishing support. Information security and regulatory controls are incorporated into delivery processes, supported by ISO/IEC 27001:2017 and NEN 7510-1:2017 certifications for work involving sensitive healthcare data. Projects are also delivered as subcontracted development for agencies or as integrated teams working alongside client stakeholders.
