Giorgos Nikolopoulos is a System Architect specializing in building data infrastructure that doesn’t just scale, but thrives under the pressure of enterprise-grade workloads. Currently leading the architectural strategy for Österreichische Post AG, Giorgos spearheaded the design of a unified enterprise data platform and a metadata-driven ingestion framework capable of processing over 80 billion rows of data. By replacing fragmented legacy systems with standardized, scalable patterns, he has laid the foundation for an AI-ready data infrastructure across the organization.With an MSc in Software Systems Engineering from UCL (Distinction), he specializes in the high-stakes execution of massive technical shifts, including a complex Synapse to Databricks migration. His approach balances low-level Spark optimization with high-level architectural governance—such as hardening security through private networking and implementing Unity Catalog.Beyond the whiteboard, Giorgos is an Instructor at Learning Actors, where he has mentored over 50 professional engineers on the intricacies of streaming, Airflow orchestration, and distributed systems. At DevOxx, he peels back the curtain on the "80 billion row" milestone, moving past the marketing hype to share the real-world architectural decisions and trade-offs required to keep a massive data ecosystem performant and secure.
