I'm Ali Emre Altuntaş, a computer engineer and SAP developer based in Ankara, Türkiye. I build business applications and integrations with ABAP and Fiori/SAPUI5, connecting user interfaces, SAP services, and backend processes.
Here, I share practical tools and implementation experience, with an emphasis on clear setup, maintainable code, and everyday use.

I start with the business requirement and consider the user journey, data quality, integration behavior, and failure cases together. I value readable code, practical documentation, code review, and validation against real business scenarios.
