ABAP · RAP · Fiori · AI-assisted

SAP development with process insight — and AI as a tool.

ABAP, RAP and Fiori from a developer with a logistics consulting background who uses AI tools deliberately. Cleanly built, upgrade-safe, with no modifications to the standard.

The difference

Most SAP developers know the code. I also know the process behind it.

Before I became a developer, I spent years working in logistics and supply chain consulting. That shapes the way I develop: I don't just ask what needs to be programmed, but why. And whether the requirement solves the problem. That saves you costly enhancements that meet the specification but miss the actual need.

The result: development that mediates between the business and the system, rather than just working through tickets. Many SAP projects fail at this interface. This is where my strength lies.

Services

What I build for you

AI-assisted development & modernization

AI tools speed up the time-consuming work: understanding legacy code, analyzing custom code, refactoring, adding missing tests. You reach your goal sooner, with no compromise on quality.

Custom development in ABAP

Tailor-made enhancements in ABAP OO, from data modelling to the finished application. Following Clean ABAP principles: readable, testable, maintainable. No sprawl that nobody wants to touch two years later.

S/4HANA-ready & upgrade-safe (clean core)

Enhancements that survive your next migration and every upgrade. Built on the official extensibility concepts instead of changes to the standard. You keep a clean core and stay release-ready.

RAP & CDS views

Modern, service-oriented development on the current SAP programming model. CDS data models and RAP business objects as the foundation for fast, future-proof applications.

Fiori / SAPUI5

User interfaces your staff enjoy using. From a single Fiori app to an end-to-end application, seamlessly connected to the backend services.

Forms & output management

Adobe Forms and SAP form development, from the invoice to the complex logistics document. Set up correctly and maintainably.

Technical support for S/4HANA migrations

Custom code analysis, adaptation and remediation as part of S/4HANA conversions. Drawn from ongoing migration projects, not from the textbook.

Approach

How I work

  1. Understand first, then build.

    I start with the process and the goal, not with the first line of code. That takes a little more time up front and saves many times as much later on.

  2. Clean work as the standard, not an extra.

    Clean ABAP, clean core, documented code that is ready for handover. You stay independent. Of me as well.

  3. Efficient through modern tools.

    I use AI-assisted development tools where they increase speed and quality: in analysis, refactoring and testing. For you, that means faster results with consistently high code quality. Responsibility for every line stays with the developer.

  4. Direct, without overhead.

    You talk to the person who does the development. No intermediate layers, nothing lost in translation.
