Siniša Bijelic, aka Prodbysinji, is a Swiss producer with Serbian and Thai roots. He started making beats at 16 and is entirely self-taught. Early collaborations with Southern U.S. artists shaped his dark, hard-hitting sound.

By 2025, he expanded into melodic West Coast styles, producing DrexTheJoint’s “Put The City On” (debuted #5 on Spotify USA). He also co-founded BLUEPRINT MUSIC GROUP, a global producer collective working with major hip-hop artists.
