What I'm looking for

I seek senior/architect roles where I can lead complex SAP S/4HANA transformations, drive integration and automation, mentor teams, and deliver scalable, long-term business value.

I am a seasoned SAP S/4HANA Solution Architect with 33+ years of techno-functional experience across GTM, CM, ACM, oil & gas, mining and resource-intensive industries. I bridge deep functional knowledge and hands-on technical skills to deliver scalable, future-ready SAP transformations for global enterprises.

My work spans end-to-end solution architecture, integration, testing and optimization, and I have led Centers of Excellence, global rollouts and complex multi-system integrations. I combine SAPUI5/Fiori, ABAP/OO, BTP, SAC, BRFplus, RPA and SAP Business AI with strong domain expertise to produce practical, high-value solutions.

I partner with Fortune 500 clients as a trusted advisor, focusing on process standardization, advanced analytics and automation to unlock efficiency and long-term value. I thrive in international, cross-functional teams and design architectures that align with strategic goals while solving immediate operational pain points.
