PortariaGo
A digital doorman operation connecting staff and residents in real time, replacing calls and scattered notices with registered deliveries, notifications and in-app responses.
Make communication match the urgency of the front desk
Building deliveries and notices often depend on calls, manual messages and operational memory. When a resident does not answer, staff repeats the contact and no reliable history exists.
The solution needed to fit the real front desk routine, distinguish buildings and roles, reach the resident phone and return an answer immediately to the person handling the delivery.
An event-driven digital intercom
Staff registers the delivery and selects an apartment. The platform sends WhatsApp or push notifications and creates a digital call with its own state for urgent pickups.
The resident receives the call and chooses whether to come down or ask the front desk to hold the package. Supabase Realtime updates the staff screen without repeated server queries.
Residents, notices, history and permissions share the same multi-tenant base, isolated per building with distinct roles for administration, staff and residents.
How it works
Registration
Staff selects the apartment, resident and delivery type.
Automation
n8n coordinates WhatsApp and the events behind the notice.
Push
FCM delivers the call to the resident native app.
Response
The resident says they are coming or asks staff to hold it.
Realtime
The front desk receives the new state without polling.
Product and engineering decisions
Realtime without polling
Changes in delivery_calls arrive through PostgreSQL events, reducing delay and unnecessary requests.
Multi-tenancy in the data model
Every entity carries its building, and RLS policies isolate operations from one another.
Mobile without breaking web
Capacitor plugins load only in native environments, keeping the same product functional in browsers.
Operational interface
