What I'm looking for

I seek hands-on SAP ABAP/HCM or S/4HANA roles focused on integrations, UI5/Fiori development and code remediation, in collaborative teams with opportunities to lead technical deliverables.

I am a Senior SAP ABAP developer with 16+ years of experience across Energy, Petrochemicals, Retail, Utilities, Manufacturing, Higher Education and Financial Operations, focused on HCM, S/4HANA remediation, integrations and custom UI5/Fiori development. I deliver ABAP RICEFW, OData services, SAPUI5 applications, data conversions, payroll and benefits integrations, and have led code remediation for HANA and S/4 upgrades.

I excel at liaising with business users and vendors for requirements, producing functional/technical specifications, and implementing robust interfaces (Dell Boomi, PI/XI, SOAP/REST, SFTP). I bring proven problem-solving, testing and documentation skills, military discipline, and a track record of successful client engagements including ORNL, Deloitte, Citgo and Baylor College of Medicine.
