Business application · Maestro Client Portal

Give your customers a really useful space

I design client portals, partner spaces and internal tools that centralize files, documents, messages, requests and indicators in a simple interface to adopt.

01 / Finding

Customer relationship fragment when each information lives in a different tool

E-mails, attachments, statutes and requests end up contradicting each other. A portal gathers what needs to be seen, asked or validated, without exposing the complexity of internal tools.

  • Status of a folder requested by e-mail
  • Documents sent several times
  • Messages without context
  • Access to manually managed partners
  • Internal team without common view
  • Dispersed dashboards

03 / Standard Maestro

The portal is designed around actions, not around the database
