I reviewed 50 promotion cases. Junior devs who got promoted had ONE thing in common.

The pattern had nothing to do with coding skills. Junior devs who moved up fast could trace a bug from the UI through the API to the database — without waiting for someone else to step in. Most juniors only understand their piece. Senior engineers understand how all the pieces connect. That's the gap. And it's teachable. This is exactly why we built our IT Fundamentals course.
