Telco churn Lakehouse and MLOps

Reproducible Databricks Medallion Lakehouse and MLOps lifecycle with execution evidence.

Technical documentationRepository

Problem

Build a reproducible data and ML lifecycle for predicting customer churn while making the synthetic nature of the dataset explicit.

Architecture

Databricks Lakehouse with incremental ingestion, a Delta Lake Medallion architecture, temporal feature engineering, MLflow, Unity Catalog and monitored batch inference.

Data flow

Synthetic data → Auto Loader → Bronze/Silver/Gold → point-in-time dataset → training and registry → simulated inference and monitoring.

Results

Contribution and authorship

  • End-to-end co-implementation confirmed by Alonso on 2026-09-14
  • MLflow experiment, three-task ML job and simulation run associated with Alonso
  • Shared work across the Medallion pipeline, model lifecycle and daily validation

Limitations

  • • The data is synthetic and the production-labelled scenario is an academic simulation
  • • Authenticated validation and deployment require an active Databricks workspace
  • • Authorship is shared and both co-authors remain credited
