Picture of Hilmi Egemen Ciritoglu

print("Hello world") 👋

I’m Egemen (he/him), a Site Reliability Engineer (SRE) at Booking.com in Amsterdam 🇳🇱, where I focus on improving the reliability of accommodation-related products by maintaining and optimizing service-level objectives (SLOs). Before joining Booking.com, I worked at Criteo, managing a large-scale, geo-distributed Kafka cluster that powered the company’s real-time data infrastructure. I hold a PhD from the Performance Engineering Lab at University College Dublin, where I conducted research on fault tolerance, scalability, and performance in data-intensive systems. My thesis, developed in collaboration with IBM Research Ireland, focused on replication management in the storage layers of systems like HDFS. Earlier in my academic path, I graduated with honours in Mathematical Engineering from Yildiz Technical University, where I built a strong foundation in applied mathematics that continues to inform my approach to computing. I’m deeply passionate about building resilient distributed systems and exploring the intersection of systems architecture, data infrastructure, and reliability engineering.
