What I'm looking for

I seek a role delivering SAP Fiori/UI5 and Java solutions in collaborative teams, on large S/4HANA or cloud transformation projects, with opportunities for technical leadership and impact.

I am a senior IT professional with 14 years of experience building enterprise applications using Java/J2EE and SAP UI5/Fiori technologies. I specialize in designing and delivering scalable UI5 applications, OData integrations, and SAP Fiori launchpad configurations for large-scale S/4HANA migrations.

My background includes hands-on work with SAP Web IDE, Gateway OData services, UI Theme Designer, and cloud deployment (Cloud Foundry), along with Spring Boot and microservices development. I have repeatedly led custom UI5 developments, enhancements of standard Fiori apps, and catalog/group creation across large programs.

I have contributed to major projects for global clients (Suncor Energy, Bell Canada, British Steel, JP Morgan Chase, Thomson Reuters, Kotak Mahindra Bank), delivering custom apps, managing UAT and bug fixes, and preparing functional and technical documentation (FSD/TSD).

I am a motivated problem-solver and fast learner who values clear requirements, robust design, and collaborative delivery; I focus on producing maintainable UI and backend solutions that meet business needs and accelerate digital transformation.
