About Sergi Caballer

3D Art Director and Creative Technologist with 20+ years shaping real-time character aesthetics and the scalable systems behind them, from feature animation at Walt Disney Animation Studios to platform-scale avatars at Meta.I lead stylized character identity across art direction, system design, and execution. The goal is straightforward: a cohesive aesthetic that holds up as teams, content, and constraints evolve.My core strength is building stylized identity systems that scale. I define parametric spaces, style guardrails, and decision frameworks to keep outputs on-model as complexity grows. Working with engineers and applied researchers, I direct personalization models that map a person’s likeness into a stylized parameter space while preserving identity. I establish evaluation standards and quality gates to keep quality consistent and repeatable.I also build the infrastructure that makes these systems shippable: tools, procedural workflows, and creator-facing pipelines that improve iteration speed, reduce variance, and keep the system extensible.Previously, I spent 9 years at Walt Disney Animation Studios, including Character Modeling Supervisor roles, and earned a VES Award for Outstanding Animated Character. Alongside studio work, I founded MeshSynergy, building creator/studio tools with topology frameworks that accelerate production while keeping standards reproducible.FOCUS AREAS:• Platform-wide 3D art vision and quality bars• Parametric identity systems, style guardrails, scalable body and face spaces• Personalization model art direction, likeness-to-parameter mapping, ML-aware workflows• Creator tooling and pipelines for real-time characters, avatars, and immersive experiences• Cross-functional execution across art, engineering, product, research, and ML

Experience

1. Art Director - Avatars

   Meta

   Jul 2023 — Present

   Lead stylized character identity and governance for Style 2.0, Meta’s latest generation of avatars. Drive scalable body and face systems and personalization across products and runtime constraints.HIGHLIGHTS• Shipped the updated avatar style system at ~2B scale. Set the creative governance and quality bar for the migration to the current style system.• Expanded the parametric identity space to 250+ identity shapes (11x increase), with guardrails that keep outputs on-model as the space grows.• Directed personalization model training, evaluation, and supervision strategy. Set vendor annotation standards and calibrated labeling. Audited 25k+ labels to keep outputs on-model.• Established cross-functional review and approval for system-level decisions across Art, Product, Engineering, and Research. Clarified tradeoffs, aligned stakeholders, and unblocked rollouts.• Delivered measurable engagement lift. In key avatar expression surfaces, DAU increased ~3–4x post update.
