Core Engineering Strengths

I build graphics and content tooling systems that stay performant, observable, and easy for artists & engineers to evolve. Below is a concise view of the durable skill surface I apply across roles.

Rendering & GPU

Real‑time / offline shading & compute features with explicit performance envelopes and profiling hooks.

  • PBR & lighting integration
  • Particles / instancing paths
  • Shader authoring & review
  • GPU capture analysis

Procedural & Data Tooling

USD / node graph workflows exposing intent early; non‑destructive layering & dependency reduction.

  • Layering & variant policy
  • Dependency pruning & cache use
  • Publish validation surfaces
  • Contextual UI affordances

Performance & Reliability

Measurement culture: budgets, instrumentation, regression nets, staged hardening before scale.

  • Frame & task instrumentation
  • Resource / memory budgeting
  • Deterministic test scenes
  • Guardrails & activation flags

Iteration & Delivery

Ambiguity → actionable slices; feedback surfaced early to keep users in the loop.

  • RFC & scope framing
  • Vertical slice prototyping
  • Integration & rollout gates
  • Adoption + impact follow‑through

Collaboration & Enablement

Translate between engine, tooling, and artist mental models; reduce opaque complexity.

  • Cross‑discipline alignment
  • Lightweight documentation
  • On‑ramp & training material
  • Healthy review culture

Technical Judgment

Bias for solutions that are testable, explainable, reversible; explicit trade‑off framing.

  • Trade‑off articulation
  • Latency vs fidelity balance
  • Risk surfaced early
  • Maintenance cost awareness

Selected Project Media

Visual slices from independent engines, simulation experiments, and rendering studies.
