Before

The challenge

Defcor's operations were running across a patchwork of SaaS tools — each with its own pricing, data silo, and lock-in. The cost of that fragmentation was growing.

Leadership needed a unified operational view and complete data ownership.

The work

What we built

A white-label business operations platform, self-hosted at app.defcor.us.

Full role-based access control with Google SSO, a complete operational dashboard, and the flexibility to extend without asking a vendor for permission. A fully owned stack with zero vendor dependency.

The approach

How it's engineered

Next.js 16 + TypeScript for the application layer. SQLite in WAL mode for the database — fast, reliable, and zero-ops. Full RBAC implemented from scratch with Google SSO integration.

Caddy as the reverse proxy for clean, automatic HTTPS. Every architectural decision optimized for ownership and long-term control.
