About the service
I am an SAP ABAP developer and help enterprise clients get real value from their SAP ERP landscape. For many years I have written and refactored ABAP code in live production systems, so I understand how to act carefully where a wrong transport can stop invoicing or lock down warehouse operations. My tasks span classic report development, dialog programs in module pool and Web Dynpro, custom transactions, user exits, BAdI and enhancement points, as well as object-oriented ABAP and CDS views that modern S/4HANA projects are built on. I read functional specifications, talk with business analysts, and turn tangled requirements into clean and maintainable code that your team can support after I leave.
Beyond individual programs, I build the connecting infrastructure that keeps the enterprise running. This means interfaces and integrations via IDoc, RFC, BAPI, OData, and REST services, data distribution through ALE, and file and queue exchange with banks, logistics, and external platforms. I design and run data migrations from legacy systems using LSMW, BDC, and modern migration tools, with verification and reconciliation so nothing vanishes quietly. I also implement SAP Business Workflow for approvals and routing, optimize slow reports, and bring inherited code into shape so it stops breaking at month-end.
I work transparently: proper transport management, documentation and handover, smooth interaction with Basis, functional consultants, and your own developers. Whether you need a quick fix, a new report, or a full integration project — I deliver stable, testable, and audit-ready code.
