At ELEKSE ELEKTRONİK PARA VE ÖDEME KURULUŞU A.Ş., I developed backend services for the Hoppa Digital Wallet platform and secure banking API integrations for transfers, card operations, and payment processing.

I designed bill-payment and recurring-payment infrastructure, and implemented KYC verification, fraud-detection, and account-restriction workflows. I also delivered customer-facing features including Request Money, Installment Payments, Value-Dated Payments, and Step & Earn.

Previously, at İŞMATİK DANIŞMANLIK, I modernized legacy Windows Forms applications and migrated core functionality to ASP.NET Core MVC. I developed HR, attendance-tracking, reporting, and query-management modules, and contributed to improving SGK-related operational workflows.
