Retail demand forecasting with the feature pipeline and the honest backtest.
Developers who work with Python, PostgreSQL, Docker and take scoped work with a fixed price and delivery date.
Cloud Deployment
Works with Docker
Trained gradient-boosted models for retail demand forecasting, with the feature pipeline that produced them and — crucially — the backtest harness with walk-forward validation, so you can see the accuracy on data the model never saw rather than on data it memorised. Weights included under a licence that permits commercial inference.
Walk-forward backtest
Accuracy on unseen data, reported per horizon. No leakage.
Feature pipeline included
The features are half the value and they are in the box.
Weights included
Commercial inference permitted. Retraining scripts included.
Honest error bars
Prediction intervals, not point estimates presented as certainty.

Ingestion, chunking, hybrid retrieval and an eval harness that catches regressions.

Deterministic replay, budget limits and traces you can read at three in the morning.
A test suite that actually fails when you break something. I checked. That is rarer than it should be.

Dropped it into a client project, rebranded it, delivered early. The structure made that easy rather than painful.

No surprises, no missing files, no "contact us for the full version". Would buy from this seller again.

Billed the saved days to a client at my normal rate. The maths on this one is not complicated.
