About Gökhan

I support companies in reliably building, managing, and successfully bringing test processes into production within complex IT and SAP landscapes. For over ten years, I have worked as a tester, test automation engineer, test manager, and test coordinator – in large transformation projects, production-critical platforms, and agile environments.

My focus areas are test planning, test coordination, test execution, and defect management across all test phases. I have extensive experience with E2E, system, integration, acceptance, load, and performance tests – in both classic and agile setups.

In the SAP environment, I take full test responsibility in S/4HANA projects, including test coverage, test case management, key user coaching, reporting, and cross-team coordination. I am proficient with SAP Cloud ALM, SAP Fiori, FI/CO, SD, CML, ILM, and Tricentis Tosca for test automation.

Whether it's test strategy, operational test execution, quality assurance, stabilization of test environments, or building sustainable regression test sets: I ensure structure, speed, and reliable results.
