emp-saas - Multi-Tenant Enterprise Management Engine

Architected a scalable, developer-first multi-tenant cloud engine centered on decentralized resource scheduling and custom event orchestration routines.

01. The Problem

Ensuring predictable execution under simulated high-throughput message stress across complex containerized scheduling routines without degrading performance.

Critical scaling constraints required immediate re-architecture.
