I'm a Senior Software Engineer based in Thessaloniki, Greece, with a background in Electrical & Computer Engineering from the Technical University of Crete. I've spent the last 7+ years designing, building and maintaining software systems across enterprise and retail environments.

Currently at Chubb, where I develop .NET applications for insurance business processes. Before that, I spent four years at Masoutis S.A. building internal tools and services for one of Greece's largest supermarket chains.

When I'm not writing code, you'll find me playing basketball or padel, watching movies, diving into games, or planning my next trip.

Distributed stream processing

SDE Spark

Synopsis Data Engine: a distributed system that maintains and queries probabilistic data structures over continuous Kafka streams, built on Apache Spark Structured Streaming.

  • ▸ Hybrid pipeline that cuts stateful operators from 3 to 1, removing two thirds of HDFS checkpoint writes per micro-batch.
  • ▸ Stateless hash routing across N slots; partial estimates are merged within the same micro-batch with no cross-batch buffering.
  • ▸ Count-Min, Bloom filter, AMS and HyperLogLog synopses, with unit, end-to-end and load-test harnesses.
