CG Animator

● Designed and implemented high-quality 3D animations using advanced illustration and digital tools, contributing to complex production pipelines, developing skills in technical creativity, spatial reasoning, and visual data processing.

● Collaborated cross-functionally with directors, developers, and technical departments to align animation deliverables with production goals, fostering agile workflows, clear communication, and rapid iteration cycles.

● Interpreted scripts and production briefs to design narrative-driven motion sequences, demonstrating strong analytical thinking and the ability to translate abstract requirements into executable outputs.

● Worked under project managers to prototype and refine real-time character behaviours and interactions in game environments, mirroring the iterative development and testing cycles used in AI system design.
