Summary
🤩
Rockstar🎓
Top SchoolDimitrios Vasilas is a software engineer specializing in distributed systems with 11 years of experience, currently building scalable storage services at Scality from Athens, Greece. His background blends industrial research and production engineering—he completed a PhD on geo-distributed query processing at Sorbonne University and then translated that research into multi-cloud object metadata solutions during an industrial PhD with Scality. At Scality he contributes to open-source projects like Zenko CloudServer, focusing on S3 protocol correctness, multipart upload handling, and robust backend object lifecycle logic. He brings deep systems thinking from earlier work on GPU virtualization and traffic simulation, enabling pragmatic design choices around derived state, performance and cost in geo-distributed systems. Known for turning research insights into tested, production-ready code, he pairs strong academic rigor with hands-on backend implementation and testing.
