xxllnc Tech Stack

Government software platform for case management and citizen services

Information Technology & Services Amsterdam, North Holland 201–500 employees Public Company

xxllnc builds software for Dutch government agencies—case-management systems, citizen contact platforms, and tax/registration applications. The stack is modern (.NET/C#, Angular, AWS, Kubernetes) but the roadmap reveals heavy lifting ahead: migrating legacy Java and Delphi applications to cloud, redesigning inconsistent design systems, and consolidating fragmented support teams. Engineering-focused hiring (6 of 9 active roles) matches the technical debt work ahead.
