About

I’m Daniel Cross (Daniel Sánchez), a software engineer working on data infrastructure at a large tech company.

Day to day I work with ClickHouse, Kubernetes, Scala/Spark, Airflow, and the usual observability stack (Prometheus, Grafana). Most of my time goes into making data pipelines reliable and fast at scale.

I write here about the things I run into: distributed systems, database internals, infrastructure patterns, and performance work. If it involves moving data between machines and not losing it, I’m probably interested.
