CINK
A personal property manager for landlords and tenants, wherever they go. Currently in development.
Overview
CINK is a property management app for landlords, tenants, agents, and managers who want control and compliance without the manual overhead: notices, checklists, budgets and taxes, documents and agreements, all run through one shared workflow instead of scattered spreadsheets and group chats. It is currently in development, running end to end on Flutter with a working sign-in, persona picker, and owner dashboard already built.
Challenge
Property owners and tenants who seek control and compliance don't have time for it: requests get lost in chat threads, paperwork lives in a dozen places, and nobody has one shared source of truth.
What I built
A shared ticketing workflow between landlord and tenant: repair requests, contract changes, meeting requests, billing and visit notices, each with a status (new, accepted, rejected, completed, cancelled) and a due date and priority. A first release keeps messaging simple by embedding WhatsApp, with an audit trail designed in from day one so a GenAI summary layer can be added later without a rebuild.
Outcome
In active development. Sign-in, the Owner and Tenant persona picker, and a real financial and property dashboard are built and running. The full-solution architecture below is the target for what comes next.
The app, running
Both sides of the desk, one Flutter build.
Live screens from the app: mocked auth for now, wired for Firebase next, with a real owner dashboard, a tenant view of their lease and payments, and the ticketed request workflow both sides share.





Personas
Everyone who touches a property, one app.
Owner
Anyone renting out a property or properties.
Tenant
A person renting a property or multiple properties.
Agent / Manager
Manages properties and requests on the owner's behalf.
Architecture
One app, a shared data lake, room to grow.
The mobile app talks to a marketing website and a CINK data lake shared across services: notices, checklists, budgets and taxes, documents and agreements, all keyed to user profiles across every role. Smart services and in-apartment devices are designed in from the start, not bolted on later.
