What I'm looking for

I am seeking SAP BASIS Lead/Consultant roles where I can improve system availability, lead upgrades/migrations, and drive operational excellence in collaborative, SLA-driven teams.

I am an experienced SAP BASIS consultant with over 10 years managing SAP landscapes across cloud and on-premises environments, delivering system refreshes, upgrades, migrations, monitoring, and performance tuning. I have led BASIS administration for enterprise clients, managed cloud builds and OS upgrades, coordinated patching, and reduced incident backlogs while maintaining SLA compliance.

I bring hands-on expertise with SAP ECC/NetWeaver, Solution Manager, Oracle/DB2/HANA, Linux/AIX, and ITIL-based processes, and have driven system performance improvements and critical-issue war rooms. I am committed to ensuring high availability, seamless operations, and continuous improvement in SAP environments.
