jeehwankeem is a sound designer based in Seoul, South Korea, working across games, advertising, film and music — from interactive and cinematic SFX to short-film sound supervision and record production.

His work includes full game sound on the 3D soulslike VELASTER, commercial work for Arcane × Meituan and Tencent's Exoborne, and sound supervision on the short film Nur einmal. To him, audio is less about making effects and more about designing the player's experience — how a scene should feel and move.

At NC AI he built and quality-controlled voice-AI training data, curating over 25,000 recordings and setting the audio quality standard — pairing sound design with a strong grasp of large-scale audio data. A HIPHOPPLAYA remix win and twelve released singles keep his ear tuned to what makes people feel something in a sound.

Available for freelance and full-time sound design.
