Project history
Designed and developed RAP-based applications using CDS View Entities, Managed/Unmanaged Behavior, Behavior Definitions, and OData V4 services. Implemented draft-enabled transactional processing, validations, authorizations, and lifecycle handling aligned with ABAP Cloud development standards. Built Fiori Elements applications using RAP annotations, integrated with S/4HANA and SAP BTP ABAP Environment. Used EML for CRUD operations, custom actions, determinations, and business logic execution. Optimized data models using CDS, AMDP, table functions, and HANA performance tuning techniques. Designed API-first, composable services using OData V4 and REST APIs. Integrated SAP with external systems via REST/SOAP APIs, CPI, IDoc interfaces, and secure OAuth-based authentication. Delivered clean-core extensibility using released APIs, cloud BAdIs, and Side-by-Side extensions on SAP BTP. Defined technical architecture (HLD/LLD) covering BTP connectivity, destinations, Cloud Connector, and extensibility patterns. Conducted code reviews, ATC checks, and enforced secure coding standards. Supported SPAU/SPDD activities during upgrades and ensured custom code compliance with ABAP Cloud restrictions.
Designed and developed ABAP on HANA solutions including AMDP, table functions, and decision tables. Provided technical guidance and mentoring to junior consultants. Managed multiple high-priority projects with on-time delivery.
Troubleshot and resolved issues in OData V2/V4, SAP Gateway, UI5/Fiori applications across multiple business modules.
