01 — The problem

ADCCUL, an African diaspora cooperative credit union, ran its entire membership process on paper — a real barrier for members spread across Cameroon and abroad who couldn't simply walk into a branch.

They needed onboarding online without losing the rigour of a real financial institution: identity verification, KYC documents, signatures, and staff review — all handled properly, with every real decision kept in the hands of staff.

02 — The process

Requirements with the client

Mapped the credit union's official paper forms and onboarding flow, then split it into two connected systems — a public website and a secure member portal — sharing one database.

Application that mirrors the forms

Rebuilt the membership application online: personal details, identity, beneficiaries, adaptive KYC uploads that change with the ID type, and an on-screen digital signature.

In-browser photo verification

Built a passport-photo checker with MediaPipe and OpenCV.js that scores face position, head pose, sharpness, lighting and background — and blocks submission until the photo passes.

Admin dashboard

Two sections — registrations and applications — where staff review, approve or reject, send reminders, and download a branded, auto-filled membership PDF with the member's photo and signature.

Secure by design

Row-level access so members only ever see their own data, private document storage, and separate test and live environments.
