Kosmas Gossis

I've delivered SAP ABAP, SLT, and S/4HANA migration work for Danone, DSM, Qatar Gas, Deutsche Telekom, Ahold/Delhaize, Merck, Nestlé, Nokia, and SAP Greece/Cyprus.

I build and optimize real-time SLT replication from ECC to Central Finance and S/4HANA, develop complex BRF+ rules, and support Datasphere, Palantir, IDoc, EDI, CDS, OData, and Fiori backend integrations. My work spans HR, SD, MM, PP, FI/CO, GTS, APO, IS-OIL, telecom, and retail environments.

I've led and coordinated nearshore and offshore teams in Budapest, Bangalore, Malaysia, and across international template rollouts, translating functional requirements into technical specifications and reviewing WRICEF deliverables.

My background in computer science and Ph.D. studies in optimisation methods supports a practical, analytical approach to system design, data migration, troubleshooting, and delivery under pressure.
