PORTFOLIO DEMO · All names, addresses and amounts shown here are fictitious. The controls below are an interactive reconstruction: edits stay in memory and disappear on reload.

01 / THE STARTING POINT

The problem was not creating a PDF.

Every month, the same information had to be found, reconciled and copied again. The challenge was keeping the landlord, property, occupants and amounts in one reliable continuum.

01 / SPREADSHEET

Data lives in a separate file.

02 / COPY

The same information is entered more than once.

03 / CHECK

The receipt needs one more manual verification.

02 / THE LIVING REGISTER

One source of truth before every document.

The product does not start with a layout. It structures the landlord, properties and tenants so each receipt reuses exactly the data that belongs to it.

03 / THE MONTHLY GESTURE

Find, select, generate.

The period supplies context. Search finds the right tenancy. An active card gathers occupants, the rental index and total before generation begins.

The button only becomes active when the document can be generated correctly.

The data is already ready.

04 / THE FINAL RECORD

A receipt is evidence, not one more screen.

The preview keeps the seriousness of an A4 document and opens in an enlarged view so every detail can be checked before it is sent.

05 / THE WORKSPACE

Daily data stays editable.

Properties carry rents, charges and references. Tenants can be an individual, a company or a shared rental. The model absorbs these cases without making the monthly action heavier.

06 / PRIVATE ACCESS

Protected in architecture, quiet in use.

CURRENT PROTECTIONS · Access is checked server-side before the workspace opens. A Firebase token and Firestore rules reserved for the owner protect professional data without making security a daily obstacle.

01 / SERVER

The password is checked server-side.

02 / SESSION

A signed cookie opens the authorized workspace.

03 / DATA

Firestore rules restrict access to the owner.

PLANNED IMPROVEMENTS · Logout, App Check, rate limiting and deployment hardening are not part of the current protections.

WHAT THE MVP VALIDATES

From register to document, without detours.

A restrained client product that replaces a repetitive spreadsheet operation with a readable business loop, delivered with a real access boundary.

01 / STRUCTURE

The domain model comes before the interface.

02 / GENERATE

A serious PDF from reliable data.

03 / PROTECT

A professional tool with no public data showcase.
