Senior🎓
Top SchoolHakan Eröztekin is a Senior Software Engineer based in Istanbul with 7 years of experience building scalable, production-grade delivery and logistics systems at Turkey’s largest e-commerce company. He blends backend expertise in Java/Go and microservices with hands-on experience in Kubernetes, Kafka, and observability tooling to drive cross-functional projects that reduced development time by 50% and are projected to save $50M annually in international cargo costs. Hakan has repeatedly stepped into leadership gaps—initiating Trendyol’s first MENA/GULF expansion effort before a dedicated team existed—while mentoring juniors and improving onboarding practices. Early work on ML-powered motion classification and CDN routing optimization shows a curiosity for algorithmic and systems-level problems beyond conventional web services.
