Message

At oXya, I administered SAP Basis operations across enterprise clients, supporting ECC and S/4HANA systems on Windows and Linux. I contributed to a greenfield S/4HANA 2020 implementation from planning through go-live.

I served as the team's go-to resource for SAP HANA, handling its installation and upgrade lifecycle, backup and recovery, performance tuning, and system replication for disaster recovery. I also contributed to a HANA scale-out hardware migration.

As primary technical point of contact for an enterprise utility-sector client, I handled database-heavy operations, reporting, compliance testing, and client escalations. I also trained incoming hires and served as de facto team lead during a manager's leave.
