Executive Summary: The blueprint I use to launch scalable SaaS products quickly without accumulating technical debt.

Building a SaaS isn't just about writing code; it's about making architectural decisions that won't haunt you 12 months later. ### My Go-To Stack in 2026 - **Backend:** Laravel (PHP 8.3) for rapid business logic development. - **Frontend:** Vue.js + Inertia.js (No separate API needed, monolithic joy). - **Database:** MySQL 8 with strict JSON column usage for unstructured tenant settings. - **Caching:** Redis for queues, sessions, and heavy query caching. - **Deployment:** GitHub Actions deploying to containerized VPS environments. ### The Importance of Repositories & Services Never write business logic in Controllers. Always use Service classes. This makes it trivial to trigger the same logic from a web route, an API route, or an Artisan console command. Start simple, but structure for scale.
