Berkay Emre Keskin
@berkayemrekeskin
I build scalable backend APIs and microservices for enterprise and AI-powered applications.
TurkeyWhat I'm looking for
I've built production-oriented backend systems at Yapı Kredi Teknoloji, developing a full-stack internal data management application with Java Spring Boot, Oracle PL/SQL, React.js, and microservices across core data domains.
I write well-tested services, reaching 90–95% unit-test coverage with Mockito and JUnit5, and have built Kafka consumers for event-driven processing. I work in Agile/Scrum teams using Jira and Git while developing task-specific SQL for enterprise datasets.
At Aselsan, I built a graph-based visualization tool using React, Redux, and React Flow to help interpret large-scale unstructured datasets and make data dependencies easier to explore.
I've also led the backend architecture for ituBNB, an AI-assisted hotel booking platform, and built REST APIs for MedAR's augmented-reality medical education workflow. My work spans Java, Python, Node.js, relational and NoSQL databases, AI integrations, authentication, and API design.
