  • E-signature

01The problem

Payment resellers collected merchant applications by hand, with no audit trail and no per-agent access control.

02My contribution

Developer on the Next.js admin portal and its Node/Express API.

03Outcome

A multi-section application flow that ends in a filled, signed agreement stored in S3, with four roles and per-tab permissions.
