Systems Engineering and Infrastructure Case Studies

Security and infrastructure work across production Laravel environments. Including incident response, infrastructure hardening, fraud prevention design, container security, and secure API platforms — focused on practical solutions for real-world operational needs.

U2C Mobile Self Service Portal

U2C Mobile Self-Service Portal

U2C Mobile is a customer portal and admin CMS built with Laravel and Livewire for a mobile carrier managing customer plans, add-ons, SIM cards, and billing. The platform serves customers who self-manage their accounts through a post-login portal.

The portal integrates with an Amdocs BSS API ecosystem for all customer data operations — plan management, product orders, payments, and SIM workflows — while AWS Cognito handles customer authentication independently from Laravel's own admin auth stack.

Firebase Admin Dashboard & API Integration

Firebase Admin Dashboard & API Integration

The LockedIn Support Portal is an internal admin tool built for the support staff of a live social mobile app. It provides structured access to customer accounts, content moderation, audit logging, and app metrics — all through a custom-built Laravel 12 + Livewire 3.4 interface. The central engineering challenge was bridging two fundamentally different data stores: a local MySQL database for staff and administrative data, and Firebase (Auth + Firestore) as the primary customer data store, accessible only via REST API.

Modular CMS Engine for Multi-Property Platforms

Reusable headless-style CMS built on Laravel and Livewire that has been deployed across multiple client projects. It provides a fully reactive admin panel for managing site content, users, settings, and system configuration — all without page reloads. The frontend is served through a Livewire component layer that reads from the same content models, making the CMS the single source of truth for every public-facing page.

The CMS was developed as a standalone foundation before any project-specific integrations were layered on top. On U2C Mobile it powers the public marketing site, blog, and static pages. The same core has been adapted for other projects involving custom CRMs and content-driven sites, with project-specific modules added without modifying the base CMS architecture.
