The Project
Overview
The Nexora Hub is an internal-grade, production-deployed digital agency dashboard built for agencies that outgrow spreadsheets and disconnected tools. It unifies every operational surface — content management, analytics, lead tracking, client reviews, newsletter subscribers, and team access — into one authenticated, role-protected platform. Built entirely custom with Next.js 14 App Router on the frontend and a hardened Node.js REST API backed by PostgreSQL with proper indexing, it delivers sub-120ms query times even at scale.
The Challenge
The Problem: Scattered Tools, Slow Teams
Digital agencies typically operate across five to eight disconnected platforms: a CMS for blogs, a separate analytics tool, a form inbox, a review aggregator, a newsletter platform, and a shared spreadsheet for service listings. Every context switch costs time. Every permission gap creates risk. The client needed one system they owned outright — no SaaS fees, no vendor lock-in, no data leaving their infrastructure.
Pain Points Before Engagement
- Content updates required 4 different logins across 3 platforms
- No unified inbox for contact form submissions — leads fell through the cracks
- Junior staff had full admin access to production settings
- Analytics lived in GA4, disconnected from internal KPIs
- Newsletter subscribers stored in a CSV with no automation
The Solution
What We Built
A full-stack agency OS. The frontend is a Next.js 14 App Router application with server components for zero-JS data pages and client islands only where interactivity is needed. The backend is a Node.js REST API with JWT authentication, refresh token rotation, and PostgreSQL with composite indexes on every high-read table. Role-based access control (RBAC) enforces three tiers: Super Admin, Editor, and Viewer.
Content Management
Rich-text blog editor with draft/publish states, SEO meta fields, slug generation, and featured image upload. Services are managed as categories + individual pages, each with their own meta. No third-party CMS dependency.
Analytics Dashboard
Embedded GA4 data via the Reporting API renders session counts, top pages, traffic sources, and conversion events directly in the dashboard. Refreshes every 30 minutes and caches to avoid API quota limits.
Lead & Form Inbox
Every contact form submission routes to a structured inbox with status labels (New, In Progress, Closed), assigned rep, and reply-by-email button. Submissions are stored in PostgreSQL, never in a third-party form tool.
Reviews Management
Staff can add, edit, and toggle visibility of customer reviews. Reviews marked visible are surfaced via a public API endpoint consumed by the main website — no manual copy-paste.
Newsletter Management
Subscriber list with import/export, segment tags, and a simple broadcast composer. Emails send via the client's transactional email provider through a single API call. Unsubscribes are handled automatically.
Role-Based Access Control
Three-tier permission model: Super Admin sees and controls everything. Editors manage content and leads but cannot touch system settings or user accounts. Viewers have read-only access to analytics and reports.
