👤
SeniorHagen Dittmer is a versatile developer with 11 years’ experience building web and data-driven solutions across Australia, currently contributing to Cliniko through Red Guava after Cliniconnect’s acquisition. He combines hands-on product ownership—having founded Hello Internets and built the Cliniko add-ons platform—with enterprise-grade SAP and AWS expertise gained in roles from SAP Developer to Head of Innovation and Development. Hagen’s background spans full-stack web work, API-led integrations, data import and ETL projects, and real-time analytics architectures, making him comfortable across cloud services, databases and IoT prototypes. He has a track record of enabling business automation and large-scale data migrations for POS and corporate clients, and continues to bridge product thinking with pragmatic engineering.
