What to actually build, the portfolio that opens interviews.

Realistic expectations
What no recruiter will tell you.
That stacking certifications shortcuts the timeline. It doesn't. Operational time and a public portfolio are what compress the path.
12–24 months from analyst or backend is the realistic time to the first role on this route. Most people overshoot by 6–12 months. Plan for it; don't panic when it happens.
