I'm 26 years old and have been working full-time in the creative field for the past two years. My strongest skills lie in mixing and mastering — areas that demand a keen ear, precision, and attention to detail. This same mindset extends to video editing: shaping raw material into a final product that tells a story, moves people, and delivers a clear message. I'm experienced in beat production, vocal editing, arrangement, release consulting, and video editing — all of which taught me how to think in terms of rhythm, flow, structure, and emotion. I’m used to taking projects from the initial idea to a polished, professional result. I love working with original creators, helping transform their vision into impactful and emotionally engaging content — whether it’s a song or a story told through visuals. ย่อ
