Hi, My favorite thing is sitting down with you one on one about what keeps you awake at night. What is really bugging you? Let's solve it together. Maybe we'll cut costs, maybe we'll improve revenue, or maybe we will do both (yay!). As an autodidact, I pride myself on learning new technologies and continually improving my skill-set. As a freelancer, I believe in professionalism, communication, clean code and representing my craft to the highest degree possible. I am offering a number of services: 1. SAP ERP Service like SAP ABAP, NetWeaver Gateway OData Services, SAP PI, SAP HANA, SAP Fiori & UI5, SAP BI, SAP BO, SAP FICO, SAP HCM, SAP MM, SAP PP, etc 2. Developing Desktop Application With C#, JavaPython 3. Developing Mobile Platform Native & Hybrid Application 4. Developing Web Application In PHP, ASP.NET, ReactJS, Angular X Version, Spring boot 5. Building Hybrid Application WIth Help of flutter & React Native
