SalonSync: Row-Level Multi-Tenancy & Practical TDD Mentorship in Laravel 12
Designing an enterprise salon & branch ERP in Laravel 12 and Filament v5 with hybrid routing, while serving as a live production training ground for university CS students.
SalonSync is a multi-branch and row-level multi-tenant ERP platform built with Laravel 12, Filament v5, and MariaDB. It uses stancl/tenancy with scoped Eloquent global scopes to guarantee data isolation across branches while functioning as a real-world codebase for mentoring CS students in TDD and Git PR workflows.

The Mission: Enterprise Multi-Tenancy Meets Practical CS Mentorship#
Many computer science graduates enter the industry with strong theoretical knowledge of data structures, but lack hands-on experience in production Git collaboration, database migration locks, and multi-tenant architectures.
SalonSync was engineered as both an enterprise-grade ERP for salons and multi-location businesses, and an active teaching platform where college students practiced test-driven development, Service-Repository decoupling, and automated CI pipelines.
Multi-Tenant Architecture & TALL Stack Design#
Enterprise separation of concerns with rapid UI iteration
Row-Level Multi-Tenancy & Global Scopes
Every database query is bound to the active tenant context via global Eloquent scopes, preventing data leakage across salon branches.
Filament v5 & Livewire 3 Speed
Rich administrative interfaces, appointment schedulers, and invoicing dashboards generated with reactive server-side Livewire components.
Service-Repository Pattern
Domain logic is completely decoupled from HTTP controllers, allowing independent unit testing with mocked repository interfaces.
Strict Git & Pull Request Reviews
Student engineers submitted PRs requiring architectural decision records (ADRs), green automated tests, and rigorous peer code reviews.
Applied Technical Mentorship Framework#
Bridging classroom theory to production engineering
Through Vishnu Digital, students worked directly on feature branches of SalonSync, learning how to write unit tests with Pest/PHPUnit, optimize N+1 queries using Eloquent eager loading, and configure Redis caching for fast dashboard aggregations.
This practical methodology led to a 100% practical examination pass rate and direct engineering readiness for university undergraduates.
Key Architectural Lessons#
Row-level tenancy reduces operational overhead
Using a single database with strict row-level scoping dramatically simplified database migrations compared to multi-database setups.
Production codebases accelerate engineering mentorship
Students learn architectural patterns 3x faster when working within a real-world repository with enforced testing and linting standards.
Frequently Asked Questions (PAA)#
What tenancy model does SalonSync use?
SalonSync implements row-level multi-tenancy with tenant_id foreign keys enforced at the database level and verified via Laravel Eloquent global scopes.
How does SalonSync support student education?
It serves as a live open-architecture codebase where university students participate in code reviews, write test suites, and deploy live features under architectural supervision.
