EstateMind

Built this for PT Adi Bintan Permata. They needed a way to track sales across their housing projects and get some insight into future performance, so I built a full-stack platform that handles both the sales management side and forecasting.

Admins can manage projects, record sales data, and see trends through dashboards. The interesting part is the prediction service: it's a separate microservice that uses ETS (Error-Trend-Seasonal) exponential smoothing to forecast sales. It tries 6 different model configurations automatically and picks the best one based on MAPE, so nobody has to tune anything manually.

What it does:

• Time-series sales forecasting with automated model selection
• Full sales record management with bulk Excel import
• Multi-project organization
• Role-based access (Super Admin and Admin)
• Interactive charts for sales trends and prediction results

The prediction service lives in its own repo: estatemind-prediction-service.
