Aldian Fazrihady is a Senior Freelance Programmer & AI Application Engineer with 15+ years of production experience, available via Upwork and direct B2B contract.

1. Production Architecture: Row & Column Window Virtualization, Web Worker Sorting & Conflated WebSocket Tick Updates

export class TickConflationBuffer {
  private buffer = new Map();
  private rafId: number | null = null;

  constructor(private onFlush: (batch: Map) => void) {}

  public push(key: string, payload: T): void {
    this.buffer.set(key, payload);
    if (this.rafId === null) {
      this.rafId = requestAnimationFrame(() => {
        const snapshot = new Map(this.buffer);
        this.buffer.clear();
        this.rafId = null;
        this.onFlush(snapshot);
      });
    }
  }
}

2. Core Architectural Guarantees

• 16ms Frame-Aligned Conflation: Buffering high-frequency WebSocket market or telemetry ticks and flushing once per `requestAnimationFrame`.
• DOM Virtualization (`@tanstack/react-virtual`): Keeping DOM node counts under 400 elements even when scrolling through 250,000 rows.
• Off-Main-Thread Filtering & Pivot Aggregation: Running heavy CSV exports and multi-column sorting inside dedicated Web Workers.
