Rockstar🎓
Top SchoolPiotr Nowojski is a Staff Software Engineer II with 14 years of experience specializing in high-performance, distributed systems and streaming platforms. As an Apache Flink PMC member and long-time contributor to Flink (and formerly Presto), he focuses on runtime stability, checkpointing, Kafka integration, and core network/processing components that power large-scale stream processing. He has led engineering efforts at Ververica, co-founded Immerok to improve Flink in the cloud, and now applies that systems expertise at Confluent. Comfortable across C++, Java, and Python, Piotr combines deep implementation skills with product-facing documentation and website contributions—an engineer who moves between low-level performance work and developer experience. Colleagues note his appetite for new CS areas and a wry sense of urgency reflected in his GitHub bio: "Hurry up, before we all come to our senses!"
