PDKS Backend System

During my internship at GBB Bilişim, I actively contributed for approximately 5 months to the backend development processes of an enterprise-scale Personnel Attendance Control System (PDKS).

Built on a multi-tenant SaaS architecture, the project provided experience in developing and maintaining scalable backend systems for multiple companies with isolated data structures.

Throughout the internship, I contributed to performance optimization, shift and time management algorithms, reporting systems, SMS verification integrations, and process management modules.

This experience allowed me to strengthen my skills in the Laravel ecosystem, scalable application architecture, query optimization, and backend solutions designed for real-world business processes.
