What drives me
Complex SAP landscapes need more than technical solutions. They need clear decisions, sound architecture and governance that works in everyday practice.
With DR Consulting, I stand for technical depth, structured thinking and independent assessment where SAP decisions have long-term consequences.
Good architecture makes complexity manageable.
About me
David Riederich – SAP Architecture & Clean Core Advisory
I combine experience in development, consulting and architecture – and therefore approach SAP landscapes holistically: functionally, technically and operationally.
My path into IT began in 2009 in an SAP-related environment. Early on, I worked with SAP technologies, ABAP and complex system structures in healthcare IT (SAP IS-H & i.s.h.med) – initially in technical roles, later increasingly close to consulting and architecture.
After a total of 4.5 years in the healthcare sector, I began my studies in Business Informatics at Johannes Kepler University Linz to expand my technical experience with a stronger business and process-oriented perspective.
From January 2020 to May 2026, I worked as an SAP consultant at a large IT service provider. In this role, I supported external client projects with a focus on Sourcing & Procurement, solution design, change processes as well as S/4HANA readiness and conversion topics. Much of my work took place in enterprise-wide multi-client landscapes – environments where process, integration and architecture decisions have long-term consequences.
Today, my focus is on SAP Governance, Clean Core, S/4HANA, SAP BTP, integration architecture and the long-term manageability of complex SAP landscapes.
DR Consulting was founded on the conviction that critical SAP decisions need an independent counter-perspective – especially where technical, business and organizational consequences converge.
Structure decisions.
Reduce complexity.
Keep systems manageable.
Guiding principle & attitude
I help companies structure decisions in a way that keeps change manageable – across the system, the organization and the architecture.
- Clarity despite complexity: Decisions based on transparency, structure and clearly defined criteria.
- Structure as a tool: Governance and architecture as means of enabling action, not as ends in themselves.
- Sustainability through discipline: Clean Core as lived practice, not as a buzzword.
Companies should understand their systems before they change them.
