Custom Analytics Dashboard for Real Estate — architecture overview

01 — The problem

Property and market data lived in several sources and was assembled by hand into weekly spreadsheets — slow to produce and out of date by the time anyone read it.

02 — Our solution

A pipeline that pulls every source into PostgreSQL on a schedule, and a dashboard with custom D3 visualisations, filters and one-click reports for client presentations.

Architecture

How it works

The pipeline, step by step — from the first input to the final output.

  3. 03

    Visualise

    Custom D3.js charts with filters by area, price band and period.

  4. 04

    Exportable reports for client presentations and internal reviews.
