Summary
👤
Senior🎓
Top SchoolMarcin Kuthan is a Technical Lead and seasoned software engineer with over 20 years of experience, focused for the past decade on big data and distributed systems. He leads Allegro’s big data team building a hybrid, 24/7 real-time ingestion and visualization platform that handles up to 5 billion daily events and peaks of 150k/sec across on-prem and GCP environments. Marcin designs and ships stateful, fault-tolerant pipelines using Kafka Streams, Apache Beam/Dataflow, Spark/Dataproc and Apache Druid, and combines low-latency Netty/Akka endpoints with Kubernetes and Mesos operations. His background spans enterprise Java, domain-driven design, and even low-level C++ replication for command-and-control systems, giving him rare end-to-end expertise from network protocol to BI UX. An active contributor to open-source tooling (notably improvements to Turnilo for Druid), he blends hands-on coding with platform-level architecture and operational ownership.
