What I'm looking for

I’m looking for a collaborative role where I can leverage SAP S/4HANA and ABAP expertise to deliver end-to-end solutions, lead technical teams, and continuously improve business processes through RAP, Fiori, and integrations.

I’m a SAP Certified Development Specialist (ABAP for SAP HANA 2.0 2022) and a Certified Scrum Master (PSM1), focused on building high-quality SAP S/4HANA solutions that drive measurable business results. I aim to grow as a technical leader while delivering on every assignment with a collaborative, delivery-first mindset.

I bring 24+ years of IT experience and 19+ years of SAP expertise across ECC and S/4HANA implementations, transformations, and AMS engagements. I’ve acted as an Onsite/Offshore Technical Lead, completing 5 implementation projects and 6 support/development projects for global clients across Utilities, Retail, Semiconductor, Energy, and Manufacturing domains.

My core strength is ABAP for S/4HANA—developing and enhancing CDS Views, AMDPs, and RAP applications, plus building SAP Fiori experiences using Gateway OData, RESTful ABAP programming, and SAP BTP. I’ve led teams (including 20 technical resources) and delivered complex interface and process improvements using IDOCs, ALE workflows, RFCs, ALV reports, BOPF, enhancements (BADIs/User Exits and in-app extensibility), and integration patterns across SAP and Salesforce (CPI/PI and related technologies).
