I am a Computer Science graduate from Özyeğin University and a full-stack software developer focused on building secure, scalable, and business-oriented applications.

I develop end-to-end software systems using Python, JavaScript, TypeScript, and Java, with experience across frontend development, backend architecture, relational databases, testing, automation, and production deployment.

I gained hands-on internship experience at CPF Türkiye, where I worked on a multi-tenant Django CRM platform and developed a Java-based Excel/XML data integration application.

My primary interests include multi-tenant applications, backend architecture, business workflow automation, data integration, role-based systems, and secure application design.
