Enterprise problems, elegant solutions.

5+ YEARS · INDIA

I've spent the last five years living inside SAP systems — writing, debugging, and optimising ABAP across real production landscapes. My focus is code that is fast, maintainable, and easy for the next developer to understand.

I work comfortably across classic ABAP (reports, module pool, BDC, enhancements) and the modern stack — CDS views, AMDP, OData, and the RESTful ABAP Programming Model on SAP HANA. For the last 1.5 years I've worked in the public cloud, extending into SAP BTP and SAP Public Cloud.

Alongside delivery I write on the SAP Community and teach newcomers — because good SAP work is as much about the people reading the code as the machine running it.
