sade.dev

sade.dev is a notebook of systems that actually run in production. I write about backend and systems engineering — PostgreSQL, Redis, Laravel, Nginx, queues and infrastructure — recording real decisions along with the constraints that forced them and the traps they hide. The aim is not another walkthrough but a reference an engineer can return to when the same decision lands on their desk. Beside the writing sits a small set of developer tools that run entirely in the browser.
