ActiveControl Web | A Change and Release Management Tool for SAP Transports

An SAP-UI5 front-end-based application with SAP gateway service as back end. I worked as a front- and back-end developer, creating the user dashboard and transport analysis dashboard using UI5. The back-end data fetching was achieved by creating Rest APIs and Odata services using the SAP gateway.

SAP-CRM 7.0 and SAP-TRM Implementation for UK Revenue

An SAP-BSP, Webdynpro, and BRF Plus-based SAP platform and application for customer master data creation, tax calculation, and accounting.

I was the front- and back-end developer for this project. The front end was written in Business Server Pages (BSP) and Webdynpro, and the back end was written in ABAP object-oriented. Being the lead developer and technical design lead, I liaised with the business to understand the process flow, design the technical architecture, create user stories in Jira, and perform sprint planning. I worked actively in building the platform with my development team members to deliver the project on time.

I had to also liaise with the SAP-PI team to integrate third-party automated file submissions and create a proxy interface.

HEMA is a Dutch variety store chain where I implemented SAP IS Retail and helped it migrate from SAP Retail 4.2 to ECC 6.0. I was the back-end developer but also worked in front-end development, creating two fully enterprise-ready SAP applications using BSP and Webdynpro.

Liaised with project functionals to incorporate custom changes to fit the business requirements and IDocs configuration and create custom IDocs for data exchange.
