I’m Andrea.
I make data
make sense.

Data engineer, open-source builder, and incurable tinkerer. I work where data pipelines, storage, and developer tools meet, usually with Rust, Python, or Go.

A few things from the workbench

Tools I build, maintain, and learn from. The source is yours to explore.

dataprof

Files, DataFrames, and Arrow streams. Quality reports that disclose what was actually assessed.

Rust · Python · Arrow

Ceres + Ares

Collecting open data and turning messy sources into useful datasets.

Rust · Open data

GitNodes

Connect decisions, incidents, and the reasons things changed. Knowledge that stays in Git.

Rust · Git · MCP

dlt + dbt

Runnable lakehouse pipelines, analytics marts, and quality gates. Also tested locally with DuckDB.

Python · Databricks

Nephtys

Supervised stream ingestion, durable events, and reproducible edge benchmarks.

Go · NATS · Edge
