SAP CAP

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).

    • 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.

Manlue LIN

ManlueChina IT PMO & Deployment Manager

I worked with David on the large and highly visible DSITI Finance Futures 2 Project which upgraded 22 Queensland State Government agencies from SAP ECC 5.0 to ECC 6.0. David performed above and beyond expectations in a highly charged environment and successfully provided ABAP solutions for a variety of standard SAP and custom functionality. His ABAP work on DSITI's customised Receipting Solution was invaluable. David has an ability to sit and listen and then discuss requirements and provide a technical solution in functional terms that a lay person can easily understand. David proved his exceptional time management skills by completing all work on time, even when he was given work with competing deadlines. David was not only an asset to the project but a pleasure to work with and I have no hesitation in recommending him for any Senior ABAP position.
