Your freelancer for custom SAP development on S/4HANA. I build intuitive, high-performance user interfaces and support your SAP standard applications — from installation through enhancement to customizing.
Four core areas that show up in every project of mine — bookable individually or as continuous support from initial requirements to go-live.
End-to-end support for your SAP projects: from requirements analysis through architecture concept to productive implementation. Concept and execution from a single source — for consistent results without friction at interfaces.
Development of high-performance SAPUI5 and Fiori applications with a focus on usability. Custom apps and Fiori Elements solutions that reflect business processes and support users productively in their day-to-day work.
Backend development in the RESTful Application Programming Model for modern S/4HANA architectures, complemented by object-oriented ABAP for legacy systems. High-performance CDS data models as the foundation for analytics and UI applications.
Modification-free and update-safe extension of SAP standard applications: Adaptation Projects, key user extensions, service redefinition, and CDS extensions. Preserve your standard baseline without compromising on individual requirements.
Focused on the core technologies of the SAP development stack. Specializing in modern development on S/4HANA — from UX concept and Fiori interface to backend logic in the RESTful Application Programming Model.
Structured three-phase approach: requirements gathering, iterative implementation, and documented handover. Transparency for business and IT — from the first conversation to the production-ready system.
Joint capture of functional and technical requirements with business and IT stakeholders. Analysis of the existing system landscape and documentation of key architectural decisions as the foundation for implementation.
Iterative development in short cycles with regular demos of working intermediate builds. Code, tests, and documentation are produced alongside the implementation — not afterwards.
Handover to your internal team with complete documentation, cleanly structured source code, and a joint walk-through. Knowledge transfer with the goal that the solution can be maintained and extended in-house.
