Beacon GTM Lakehouse

A B2B sales lakehouse you can run on a laptop.

What is it?

A complete go-to-market data platform, from raw sales events to a live dashboard, that spins up on a laptop.

Why I built it

To show a full modern data stack end to end without a cloud account.

What I actually built

  • Bronze → Silver → Gold medallion architecture in PySpark.
  • Postgres serving layer, Redpanda streaming, Airflow orchestration and a Streamlit dashboard.
  • All running in Docker with no cloud account needed.
