A website, realtor app, office

A website, realtor app, office desk and developer portal on one database. Every sale is checked against its receipt, so no plot is ever sold twice. The client. A realtor network in Ibadan. Realtors join through someone already in the network and sell estates plot by plot for developers. Before this, the work ran on a WordPress portal, WhatsApp and spreadsheets.

The problem.

Payment receipts were checked by hand on WhatsApp, and some were lost, reused or faked.

Nothing stopped two realtors from selling the same plot.

Who brought in whom could be changed quietly.

Developers couldn’t see what was selling.

What I built. One platform with four parts:

Public website: live estates showing plots left, and a clear path to join or list an estate.

Realtor app (phone-first): your circle of people, estates to sell with a live plot map, and a receipt upload that holds the plot the moment it’s sent.

Office: one Desk for every decision, with a recommended answer for each receipt (amount short, wrong sender, reference already used). Estates, the network tree, members, sales and a full audit log.

Developer portal: developers watch their own plots sell, without seeing the network.

How.

I started with research: a teardown of the competitor, what each user needs, and the hard problems written down before any code.

Then design: three concepts, sign-off, and a sample of every screen before building it.

The rules live in the database, not the screens. A plot becomes sold only when its receipt is approved, a plot can’t have two live sales, and an upline only changes with a written reason. The audit log can’t be edited.

Over 100 automated security checks prove each person only sees what they should.

Outcome. A network that runs on proof instead of screenshots in a chat, and an office that clears a day’s receipts from one screen.
