Tuğrul Yıldırım

CRM/ERP Developer & API Integration Specialist

Professional Summary

I design and deliver bespoke CRM and ERP systems for sales, operations, finance, manufacturing, and wholesale workflows. My work focuses on explicit record ownership, duplicate handling, approvals, and integration boundaries rather than treating a new interface as the solution by itself.

My approach prioritises process-led development over generic templates. I map current shop-floor and back-office flows before implementation, then define governance, security controls, API contracts, acceptance criteria, and handover documentation for the agreed scope.
