Abdelrahman Elsayed — Frappe Developer & ERPNext Specialist

02— About

A developer who bridges data and business.

I started as a Data Engineer on Upwork — building ETL pipelines, cloud-native analytics stacks, and Python packages. After 3+ years and 45+ successful projects, I transitioned into Frappe/ERPNext development.

That background isn't a detour — it's a practical advantage. While most Frappe developers struggle with data-heavy reports and integrations, I find them straightforward. I understand both the business workflow side and the engineering side.
