About

Calleum Pecqueux. Systems engineer in Sydney, Australia.

I work on Rust backends and infrastructure, and I spend my evenings building a PostgreSQL-style storage engine.

Before that: five years of Java microservices and platform work, which gave me an unhealthy interest in GC logs, lock chains, and migrations that were not allowed to stop.

This site is notes. Mostly on:

• Rust and systems programming
• Database internals
• Infrastructure and the failure modes it hides
