At Istanbul Esenyurt University, I develop and maintain C#/.NET web and desktop applications as a solo developer, working across backend services, databases, integrations, and deployment.

I built and deployed an LDAP-integrated Self-Service Password Reset system for internal account recovery workflows.

I also developed the KGS Card Access Control System, integrating ACS-551 card readers and OBS API automation for card access processes.

I implemented Hangfire jobs for card authorization, access-log collection, and student-data synchronization, and support Docker/IIS deployments and production troubleshooting. At Migros Ticaret, I supported data validation, RabbitMQ issue investigations, and Python script monitoring.
