About

Oracle PL/SQL and APEX developer with over 9 years of experience in the telecom and manufacturing sectors. I currently build advanced PL/SQL solutions and cross-system integrations for Türk Telekom's inventory management systems. In previous roles, I delivered ERP systems end to end, spanning human resources to production and MRP to shipping, covering analysis, database design, development, go-live and user training. My industrial engineering background helps me understand business processes and turn them into sustainable technical solutions.
