Hi I'm David.

Accelerating Cloud-Native Application Development on SAP BTP.

I design and build lightweight, enterprise-grade cloud applications and microservices leveraging the SAP Cloud Application Programming Model (CAP). By combining open-source technologies (like Node.js/TypeScript and Java) with powerful SAP frameworks, I create scalable, future-proof solutions optimized for the SAP Business Technology Platform (BTP).

• Core Deliverables:

  • End-to-end cloud application architecture utilizing Core Data Services (CDS).

  • Development of custom OData (V2/V4) and REST APIs for cross-system data exchange.

  • Seamless integration with third-party systems and external SAP cloud services.

  • Multi-tenant application deployment tailored for scalable enterprise business models.

Building Next-Generation, Cloud-Ready Applications inside the ABAP Cloud.

I deliver high-performance, transactional business applications optimized for SAP S/4HANA (Cloud and On-Premise) and the SAP BTP ABAP environment using SAP RAP. This modern development framework represents the intrinsic future of ABAP. It allows me to build robust backend architectures directly integrated with SAP’s database capabilities, ready for modern web applications.

• Core Deliverables:

  • Design of semantic data models via advanced CDS Views and Metadata Extensions.

  • Implementation of transactional business logic (Create, Read, Update, Delete - CRUD) with strict Draft handling capabilities.

  • Building rich backend APIs perfectly tailored to fuel responsive SAP Fiori Elements UIs.

  • Crafting custom business actions, validations, and rigid authorization controls.
