Kyriakos Psarakis

I am a Software Engineer at Ververica, where I work on stream processing systems that power large-scale, real-time data applications. I enjoy building systems that make data processing more intuitive, scalable, and developer-friendly; helping shape the next generation of data platforms.

I completed my PhD at TU Delft, where I worked at the intersection of stream processing and serverless computing under the supervision of Asterios Katsifodimos. My research introduced Styx, a distributed streaming dataflow engine that provides high-performance serializable transactions for stateful cloud applications. Styx aims to make microservice development easy and accessible for everyone by combining the programmability of high-level languages with the scalability and fault-tolerance of modern stream processors.

Prior to that, I obtained my MSc in Computer Science at TU Delft with a thesis on Holistic Schema Matching at Scale in collaboration with ING Bank Netherlands. My first degree was a diploma (Integrated Master’s) in Electrical and Computer Engineering at the Technical University of Crete.
