Overview

A scaling game lives or dies on its data layer. I script session-locked persistence with safe load/save, retry handling, and migrations so player progress and economy survive crashes, teleports, and high concurrency.

Scope: Session locking, safe save/load, retries, and schema migration

Highlights

  • -Session locking prevents the same profile loading on two servers
  • -Safe save/load with retries guards against transient failures
  • -Schema migrations let data evolve without breaking old saves

The strongest fit is work where reliability, scale, or technical risk matters enough that proof and judgment carry more weight than a generic dev retainer.
