Welcome to the GeeksLab Ecosystem

The Deconstructed Dev

Understanding every layer of the stack, from pixel to packet.

Built for remote delivery: interfaces that convert, APIs that don’t page you, and infra you can trust from any time zone.

Layer 1Remote-ready delivery

Frontend

Interfaces that convert on first impression.

Learnings

  • Geo-segmented caching yields better P95 than fixed TTL
  • Silent revalidation avoids cold starts during campaigns
