What the system does
Properties
Add and manage all your properties in one place — details, documents, and status at a glance.
Tenant management
Sign tenants, store their details, and track lease history across every property.
Leases & rent
Raise the rent, track what's paid and what's overdue — all automated.
Dual portals
Separate landlord and tenant portals — each user sees exactly what they need.
How it is put together
Front ends
Two web apps — one for landlords, one for tenants — behind a shared REST API.
Microservices
Auth, billing and contracts split into small services that scale on their own.
Workers
A PDF contract generator plus an email worker that sends rent notices and receipts.
Storage
MongoDB keeps the records, Redis handles sessions and queues, all inside Docker.
