I have over five years of experience in SAP ABAP development, during which I have worked on various projects involving customizing SAP modules, developing reports, and creating interfaces. My experience includes working with SAP ECC and S/4HANA, where I have developed and maintained complex business processes, enhanced existing functionalities, and resolved critical issues. I am proficient in ABAP Objects, BAPIs, BADIs, and AMDP, and I have a strong understanding of the SAP development lifecycle.

Debugging and troubleshooting in SAP involve a systematic approach. I start by analyzing the error messages and logs to identify the root cause. I then use tools like the ABAP debugger, trace files, and transaction codes to trace the execution flow and pinpoint the issue. Once identified, I apply appropriate fixes, which may involve modifying code, adjusting configurations, or updating data. I also document the steps taken and the solution for future reference, ensuring that similar issues can be resolved more efficiently in the future.

I have extensive experience with SAP Fiori and UI5 development, having worked on multiple projects to create responsive and user-friendly applications. My experience includes designing and developing Fiori apps from scratch, customizing existing ones, and integrating them with backend SAP systems. I am proficient in using SAP Web IDE and Visual Studio Code for development, and I have a good understanding of OData services, annotations, and the Model-View-Controller (MVC) architecture. I also ensure that the applications comply with SAP’s UX guidelines and best practices.

Ensuring quality and performance involves a combination of best practices and tools. I follow a rigorous testing process, including unit testing, integration testing, and user acceptance testing (UAT). I use ABAP Unit for automated testing and ensure that all code is peer-reviewed before deployment. For performance, I conduct load testing using tools like SAP LoadRunner and analyze performance logs to identify bottlenecks. I also optimize SQL queries and database access patterns to improve response times. Continuous monitoring and regular performance tuning are integral parts of my development process.

I have significant experience with SAP integration technologies, including SAP Process Integration (PI) and Process Orchestration (PO), as well as SAP Cloud Platform Integration (CPI). I have designed and implemented integration scenarios using these technologies, including synchronous and asynchronous communication, message mapping, and transformation. My experience includes working with various adapters, such as IDoc, SOAP, and REST, and ensuring seamless integration between SAP and non-SAP systems. I also have experience in monitoring and troubleshooting integration issues, ensuring high availability and reliability of the integration processes.
