Hi, I’m Júlio Ferreira Junior, a self-taught Audio Engineer with over 20 years of experience in music production, mixing, and mastering. I work with both analog and digital workflows, blending hands-on studio techniques with modern tools to deliver broadcast-ready results. I collaborate with artists across Africa and beyond, building a workflow that emphasizes sound quality, precision, and creative collaboration. I’m now exploring opportunities at the intersection of sound and AI, applying my deep understanding of sound structure, editing precision, and quality evaluation to AI-driven audio systems and datasets. I’m enthusiastic about how human listening expertise can inform machine learning and data labeling for better audio intelligence.
