🏅 Certifications
Part of the Resources Library — SQL Engineering Handbook
Certifications don’t replace a portfolio — the projects in projects/ do more for a job application than a badge does. But a recognized certification is a fast, external signal of a specific skill, and worth it once the underlying skill is already real.
