Summary
👤
Senior🎓
Top SchoolKoray Geçici is a seasoned software architect and backend engineer with over 20 years of experience building scalable, secure systems—currently focused on microservices, Kafka-driven event architectures, and containerized deployments on AWS EKS. He moved from managing large multi-team programs in payments (Mastercard/PayCore) back to hands-on development to stay close to system design and coding, bringing rare cross-cutting expertise across ATM/pos acquiring, card issuing, and payment gateways. Technically fluent in Java, Spring Boot, Kafka, Neo4j, Docker, and CI/CD tooling, he has a strong track record migrating monoliths to cloud-native platforms and achieving high test coverage and operational observability. As an independent consultant he now helps financial services modernize microservice landscapes, while his background includes building regionally deployed Lambda integrations and custom Kubernetes tooling for per-user pod provisioning. He pairs deep domain knowledge of payments and EMV standards with practical engineering craftsmanship and an MBA that informs cost-efficient, secure architectural decisions.
