Cesar Heiberg Ramirez Sieber is a Los Angeles based 3D artist, architect, and digital creator working across product visualization, animation, environment art, and 3D printing.

I’m a Los Angeles based 3D artist, architect, and digital creator with a passion for bringing ideas to life through high quality visuals. My background in architecture has given me a strong foundation in design, composition, and problem solving, while my experience in 3D art allows me to create everything from product visualizations and architectural renders to stylized assets, environments, animations, and 3D printed creations.
I enjoy combining creativity with technical precision to build work that is both visually compelling and functional. Whether I’m creating for marketing, games, film, or product design, my goal is always to deliver high quality work that tells a story and leaves a lasting impression.
I’m always looking for new opportunities to collaborate with studios, brands, and creative teams on exciting projects.
