Building pipelines
that move data forward.

I design and deploy data infrastructure — ETL pipelines, network monitoring, and automation systems running on self-hosted hardware.

Network Dashboard
A live network monitoring tool running on a Raspberry Pi 400. Executes automated speed tests and logs results over time — built as a foundation for broader network diagnostics and home infrastructure monitoring.

about Who I am

I build data pipelines and self-hosted infrastructure. My current setup runs on a Raspberry Pi 400 — small hardware, real workloads.

I'm focused on practical systems that collect, move, and surface data in useful ways. This site is itself hosted on the same Pi running my projects.
