Tech 301 – Senior Practitioner
Business-Critical Microservice Owner
Program Overview
Tech 301 develops engineers capable of owning an entire microservice as a business asset — accountable for uptime, cost, security, scalability, and roadmap alignment.
The transition is from feature ownership → operational accountability.
