Experience
End-to-end SAP BW/4HANA Greenfield Implementation
I delivered a greenfield SAP BW/4HANA implementation from system installation through production go-live. I also designed data models following the LSA++ architecture, including ADSOs and CompositeProviders, and optimized transformations. I set up development, QA, and production landscapes, transports, and process chains, building enterprise KPIs and reporting layers using BEx and SAP Analytics Cloud. Finally, I provided production support and knowledge transfer post go-live.
SAP with Databricks Unified Analytics Platform
I integrated Databricks with SAP BW and Datasphere to process large-scale, non-SAP datasets, enabling advanced analytics use cases by harmonizing SAP transactional data with external data sources. I also designed scalable pipelines and ensured data availability for enterprise reporting while validating and reconciling outputs between Databricks and SAP systems.
Global S/4HANA and BW/4HANA Data Migration
I supported a global migration from ECC to S/4HANA and BW to BW/4HANA, handling data mapping, transformation, and reconciliation activities. I also designed SQL-based migration validation frameworks to compare legacy and target systems, ensuring data completeness and accuracy. Additionally, I built BW/4HANA models and CompositeProviders aligned with the new S/4HANA data structures. Throughout the migration, I collaborated with functional teams, including SCM, procurement, and inventory, to align business rules with migrated data. I supported UAT, cutover activities, and post-go-live hypercare, ensuring a smooth business transition, handling data migration for the entire historical data.
SAP SCM Analytics for Supply Chain, Procurement, and Inventory
I delivered end-to-end SCM analytics solutions for supply chain planning, procurement efficiency, and inventory visibility. I also conducted requirements gathering with functional teams and translated business processes into BW models and KPIs. I built custom SAP DataSources using ABAP on top of tables, CDS views, and function modules. Additionally, I designed advanced BEx queries on CompositeProviders with CKFs, RKFs, conditions, and exceptions, ensuring high-performance reporting for business users.
