Deep-dive technical whitepapers on deterministic game loops, WebGL 2.0 sprite batching, GPU particle systems, spatial partitioning algorithms, and modern interactive canvas architectures.
Algorithmic dungeon and terrain synthesis: 4-5 rule cave generation with cellular automata, coherent Perlin noise heightmaps, and bitmasked autotiling systems.
Clean game architecture: implementing deterministic State design patterns, entry/exit transition hooks, player movement states, and enemy behavior trees.
Reducing collision complexity from O(n^2) to O(n log n): recursive Quadtree bounds subdivision, grid-based spatial hashing arrays, and broadphase filtering.
Interactive game audio engineering: audio graph architectures, distance attenuation models (HRTF), real-time impulse response reverbs, and adaptive vertical layering.
Optimizing 2D grid pathfinding: standard A* bottlenecks, Jump Point Search pruning heuristics, hierarchical map clustering, and web worker threading.
Algorithmic asset optimization: MaxRects 2D bin packing, power-of-two (POT) texture constraints, GPU memory alignment, and JSON texture atlas schema.
Rigid vs skeletal animation: hierarchical bone matrices, inverse kinematics (IK), mesh deformation skinning, and lightweight JSON animation runtimes.
Optimizing 2D graphics throughput: dynamic Vertex Buffer Objects (VBO), interleaved vertex attributes, texture unit indexing in shaders, and batch flushing heuristics.
Migrating legacy Flash animations: Adobe Animate HTML5 Canvas publishing, CreateJS / EaselJS stage lifecycles, symbol hierarchies, and vector optimization.
Designing deterministic game loops in JavaScript: requestAnimationFrame vs setInterval, spiral-of-death prevention, semi-fixed timesteps, and alpha blending render interpolation.
Architectural breakdown: PixiJS low-level WebGL scene graph vs Phaser 3 full-stack game framework, arcade physics, tilemap loaders, and memory management.
Simulating 100,000+ particles at 60 FPS: computing physics completely on the GPU with WebGL 2.0 Transform Feedback buffers, ping-ponging, and instanced draw calls.
