Build hardware-accelerated charting and order-book rendering systems utilizing Canvas, WebGL/WebGPU (Web), Impeller/Skia (Flutter), and Metal/Vulkan (Native Mobile) to guarantee deterministic 120 FPS performance.
Manage memory and thread optimization by eliminating garbage collection pauses, UI thread blocking, and frame drops through memory pooling, background Web Workers/Isolates, and lock-free data structures.
