Demand Forecasting with
Machine Learning

An operations director needs weekly demand forecasts to plan inventory. You'll explore historical order patterns, engineer time-series features (lags, rolling averages, seasonality), train and evaluate models against honest holdouts, and ship a portfolio piece that balances analytical rigor with production-thinking. Advanced — assumes pandas + basic ML comfort.

Full project workspace, live PostgreSQL DB, AI Project Mentor & verified credential

What you'll learn

  • —Frame a business question (weekly inventory planning) as an ML forecasting problem
  • —Engineer time-series features (lags, rolling stats, seasonality flags) without leaking the future into the past
  • —Compare baseline and ML models honestly using time-series cross-validation
  • —Reason about model deployment: cadence, monitoring, when to retrain
  • —Ship a portfolio repo that demonstrates both analytical rigor and production-thinking

After this project

What you'll be able to claim — credibly — once your repo is shipped.

Roles you can credibly apply to

Junior Data Scientist (time-series)
End-to-end forecasting — from problem framing to honest evaluation to deployment thinking — is the exact loop hiring managers test for in junior DS roles.
— Pair with at least one classification or causal-inference project to show you're not a 'forecasting only' candidate.
ML Engineer (entry-level)
The production-thinking section (cadence, monitoring, retraining) is what separates 'student model' from 'production-ready' work — directly relevant to MLE roles.
— MLE roles often expect engineering rigor (Docker, CI, model registries); this project shows the conceptual layer, not the infra layer.
Forecasting / Demand Planning Analyst
Operations + supply-chain teams hire specifically for demand forecasting — domain experience with weekly horizons and seasonal patterns transfers directly.
— Industry-specific (retail, CPG, logistics) signal helps; this is an ecommerce framing.

Interview questions you'll be ready for

  1. 01Walk me through how you'd frame 'I want better demand forecasts' as a concrete ML problem — including what metric you'd optimize.
  2. 02What's the single most common mistake in time-series feature engineering, and how do you prevent it?
  3. 03Your seasonal-naive baseline beats your fancy XGBoost by 5%. What does that tell you?
  4. 04How would you set up time-series cross-validation differently from random k-fold, and why does it matter?
  5. 05If your model's deployed and starts drifting, what would your monitoring actually catch — and what would it miss?
Resume-ready bullets — unlocked when you reach Milestone 5
After completing the project, you'll get a copy-ready resume bullet template phrased the way hiring managers want to hear it, with the numbers your own analysis produced.

The 5 milestones

Each milestone is reviewed before you advance.

  1. 01

    Set up your project repo

    Milestone 1

    Before any analytical work: create a public GitHub repository, push the standard skeleton, and paste the URL into your workspace.

  2. 02

    Frame the problem and explore the demand data

    Milestone 2

    Translate the operations ask into a forecasting problem and form a first-pass mental model of the demand patterns.

  3. 03

    Engineer time-series features

    Milestone 3

    Build features from order history without leaking the future into the past.

  4. 04

    Train, evaluate, compare

    Milestone 4

    Build a baseline, build an ML model, evaluate both honestly with time-series cross-validation.

  5. 05

    Production thinking and portfolio

    Milestone 5

    Wire the analysis into a deployment-ready story and polish the repo for a recruiter.
