What We Shipped

Operations This Week

The invisible work that keeps the platform fast, reliable, and cost-efficient.

Search Infrastructure Right-Sizing

Our search servers were memory-heavy but CPU-starved. We swapped all 4 to speed-optimized machines and trimmed excess memory causing system freezes.

$390/month saved (~$4,680/year) · Search speed restored to healthy levels
