ABOUT KONSTANTINOS EFTAXIAS
Senior Data Scientist and researcher working at the intersection of Machine Learning, Audio Intelligence, and Large-Scale Systems. My background spans machine learning, signal processing, and mathematical optimisation — combining academic depth with hands-on experience building production-grade AI.Currently focused on scalable AI solutions for the music and media domains, including developing similarity search architectures and training feature extractors for noisy audio data. This work involves fine-tuning models and designing vector database pipelines to support efficient content discovery, recognition, and retrieval tasks across large datasets.I’m passionate about bridging research and engineering — turning innovation in machine learning into resilient, real-world systems. My interests include scalable ML infrastructure, distributed optimisation, computer audition, and multi-modal learning connecting vision, sound, and context.
