🔷 Tech 401 – Tech Lead / Architect
Zero-Downtime Platform Transformation Leader
Program Overview
Tech 401 prepares leaders to design and execute platform-level migrations without business disruption.
This level transitions from service accountability → ecosystem-level architecture governance.
Program Objectives
Execute strangler-pattern platform migrations
Implement CDC & dual-write transition strategies
Govern progressive rollout frameworks
Align architecture decisions to business risk
