Estúdio Dupla Face
Marketing site and project-tracking platform for a São Paulo architecture studio, with an interactive floor plan, a client portal and realtime messaging.
Pins that hold at any size
Each pin's coordinates are stored as a percentage of the image, not in pixels. The marker stays exactly over the right room at any screen width and any zoom level — a small detail that decides whether the feature is usable on a phone at the building site.
Protection lives in the database
Every table has Row Level Security, and the policies rest on three functions: is_admin(), is_approved() and row ownership. An approved client sees only their own projects, conversations and documents — even if the interface gets it wrong.
Private documents, expiring links
Documents live in a private bucket with the client id as the first path segment, and downloads go through a route that re-checks ownership before signing a 60-second URL. A leaked link stops being a problem a minute later.
A record of decisions already described in the case study; no release date assigned. New changes can be added as dated entries.
