Instructor

Wen-Chi Lin spent twelve years across wholesale voice and fixed-mobile assurance desks before designing Connectapicloud curricula. She still marks Settlement Floor narratives personally and keeps clinic groups small enough that every participant presents at least once.

Reviews

“Module 05 finally made our roaming sample plan match how TAP files actually arrive.”

“Clinic feedback on my governance memo was sharper than our last external review. I wanted more prepaid labs; we supplied our own.”

FAQ

Do I need a production financial auditing app to enroll?

No. We teach governance patterns that map to common app workflows, but labs run on provided extracts. Bring your own exports if you want tighter fit.

What is a real limitation of this course?

We do not simulate every vendor’s mediation UI. Labs emphasize portable evidence standards. Teams on highly customized stacks still need a short internal orientation after enrollment.

Are live clinics required?

Ledger Desk is fully self-paced. Clinics are included in Settlement Floor and Carrier Atelier, or available as a Single Clinic Pass.

Is there a certificate?

Yes — a completion statement listing modules finished and any clinic attendance. It is not a regulated license.
