Nikolaos Konstantinou is a Data Team Lead with over two decades of hands-on experience building scalable data and knowledge-driven systems across academia, startups, and enterprise environments. He blends academic rigor—a PhD in semantic web and distributed knowledge systems—with operational pragmatism, having co-founded a data-focused startup and led award-winning research in real-time data, sensor networks, and digital libraries. At THG he progressed from Senior Data Engineer to leading data teams, designing robust pipelines, knowledge engineering, and ML-ready architectures that prioritise data quality, fairness and reliability. He is equally comfortable coding backend systems and teaching algorithms, and has published in top-tier venues while mentoring engineers across industry and university settings. A detail that sets him apart is his longstanding focus on structuring fragmented information into actionable knowledge, which repeatedly turns messy data into strategic assets.
