SAP Cloud Integrator on Public Cloud

Led a team in the deployment of SAP landscapes onto the Azure platform. The project involved designing scripts to automate SAP infrastructure deployment on the public cloud.

This was originally a very fragmented and independent process that I re-designed and turned into an organized architecture where each completion of a step triggered the start of the next one. This gave us far greater control of the process, made it less error-prone, and protected us from when the process would fail in the middle.

SAP CPI initially and now SAP BTP is used as a major SAP intelligent enterprise product to connect SAP and Non SAP systems on the cloud and on-premises using hubs like APIs and cloud connectors.

Designed and Implemented SAP S/4 HANA Cloud Edition With RiSE Offerings by SAP

Designed and implemented SAP S/4 HANA cloud edition with RiSE offerings by SAP.

The business had a closely guided journey to cloud adoption and S/4 HANA Cloud implementation and the ability to analyze and improve the company during and after the implementation process. It was also able to extend those business processes where necessary in an agile and scalable way.

HANA Migration for A 12 TB Database Using DMO Tool Within Stipulated Downtime Window

I managed the team for the end-to-end upgrade and migration of SAP ECC 6.0 from Linux Oracle, on-premises, to Linux HANA 2.0 for SAP S/4 HANA hosted on AWS Cloud.

This was a unique project where a 12 TB database was migrated using the DMO tool within the stipulated downtime window, and SLA was not breached. The team was customer-awarded based on the project's success.

Integrated SAP S/4 HANA and OpenText Applications

Worked with a team to implement and integrate SAP S/4 HANA Cloud Edition with OpenText VIM 20.4 versions.

We used pre-configured rules, roles, and actions for the solution to support custom document processes. It optimized and automated end-to-end processing from receipt to posting and included procedures for invoices, sales orders, and delivery notes.
