Data Engineering for Machine Learning
Learn and build the practice of data engineering for machine learning — share field notes, study living reference platforms, and grow skills that hold up under production pressure.
Reference platforms
Two production systems the community uses as living examples — a control plane and a streaming data plane.
PRIMARY · DATA PLANE
FORJD
Universal secure streaming engine — sealed ingest, YAML workflows, durable projections, analytics, and a Rust hot path for production pipelines.
Open FORJDLEARNING · CONTROL PLANEDEML
Learning library and Firebase-authenticated control plane — identity, billing, consent, dashboards, and status surfaces that call FORJD.
Open DEMLLearn with the community
Field notes, the book, and the whitepaper — community content without product chrome.
