Summary
👤
Senior🎓
Top SchoolConstantinos Dimitriou is a Senior Machine Learning Engineer with 11+ years building advanced audio and multimedia ML systems for products used across entertainment and media. He has driven production-grade research from source separation and vocal enhancement to transformer-based entity matching, combining deep learning, DSP, and robust training techniques to reduce artifacts and hallucinations. At Antares he led ML innovations for vocal prep and generative pitch models; prior roles at AudioShake and Gracenote produced state-of-the-art separation, lyrics alignment services, and multimodal embedding systems deployed in real products. He blends research rigor with practical engineering—designing datasets, evaluation protocols, and cross-team quality pipelines—to move models reliably into production. Based in San Francisco with a master’s in Sound & Music Computing and a BSc in Mathematics, he brings a rare mix of audio signal intuition and scalable ML engineering. An early background in music composition and web development subtly informs his product-oriented approach to audio research.
