Solution architecture.
Delivery leadership.
Hands-on engineering.
Cross-disciplinary IT consultancy for complex programmes across public and private sector clients.
From design through to handover
Most architecture work stops at sign-off. Callaghan IT Services takes solutions through to operational adoption, across architecture, engineering, programme management, and the spaces between.
Architecture
Networks, identity, ERP platforms, cloud, integration. End-to-end solution design with the full set of artefacts.
Delivery
Programme leadership, supplier coordination, hands-on engineering through migration weekends and cutover events.
Adoption
Training, runbooks, governance, operational handover. Designs that get used, not designs that get filed.
