Jonathan Reinink is a Canadian software engineer and the creator of Inertia.js — the modern monolith framework that lets Laravel and Rails developers build SPAs without the typical SPA complexity, by treating server-rendered pages and client-side React / Vue components as a unified stack.
His CourseFlix listing carries Eloquent Performance Patterns — a deep treatment of Laravel Eloquent ORM performance: the query patterns, the N+1 traps, eager loading strategies, and the engineering decisions that separate fast Eloquent code from the default slow patterns.
Material is paid and aimed at Laravel developers running Eloquent at scale. For broader content, see CourseFlix's Laravel category page.
