Message

At Turkish Airlines Technology, I re-engineered legacy ticket-reconciliation batch jobs, reducing runtime and eliminating recurring production failures. I also built Spring Batch reconciliation flows and shipped dashboard features for internal audit users.

At ING Technology, I refactored loan-origination modules from a legacy monolith into Spring Boot microservices. I contributed to architecture reviews and helped teammates get onboarded to the new architecture.

Across Vodafone and Anadolu Sigorta, I built backend services for CRM and digital insurance products, and contributed to customer-facing mobile applications. My work included improving customer-lookup API performance and developing features with Ionic and React Native.
