Jack Rabbit Wine Club Admin Platform

A full-stack admin module for the Jack Rabbit Wine Club loyalty platform — a four-surface product (consumer web, admin dashboard, native mobile app, and Sanity-powered CMS) built for one of Vinarchy's wine brands under Quantum agency. Hyperyond owned the admin end of the platform top to bottom: API, schema, auth, UI, dashboard, and reporting.

Project Overview

For Vinarchy's Jack Rabbit Wine Club brand, working under Quantum's brand and product direction, Hyperyond shipped the entire admin module of the loyalty platform — the operations surface that the Quantum and Vinarchy teams use to run the program day to day. The platform itself is a Turborepo monorepo with web, admin, mobile, and Sanity-studio apps; we owned the admin app end-to-end and contributed to the shared packages and Supabase schema where the admin module touched them.

The admin is live in production at admin.jackrabbitrewardsme.com and continues to operate as the core ops surface for the program.

Role Division: Quantum led brand strategy, product direction, and the consumer-facing surfaces. Hyperyond owned the full-stack delivery of the admin module — frontend, API, auth, schema work, and the analytics dashboard at the center of it. Roughly two months, end to end.

What We Built

Operations Surface (12+ Feature Areas)

Members CRM — list, detail, search, edit, with linked points balances and order history.
Orders — full order management with detail pages and a B2B reporting view.
Registrations — onboarding queue with stats and per-record review.
Points & Rewards — balance management, ledger, and integration with Sanity-driven rewards catalogue.
Scratch-card Gamification — full engine for the consumer scratch-card promotion: prize pools, weighting, image uploads, and per-card auditability.
Promo Codes — generation, distribution, expiration tracking, and bulk export.
Reviews & Testimonials — moderation and approval workflow.
Audit Log — compliance-grade activity log spanning every admin action.
Role-Gated User Management — admin-side user CRUD with role assignment.
Login + Login Logging — auth surface with structured login telemetry.
Reports — dedicated views for emails, orders, and analytics.

Unified Analytics Dashboard

The centerpiece of the admin module. We engineered a single live dashboard that consolidates data from across the program — members, orders, points, rewards, scratch-cards, and Klaviyo email metrics — into a cohort-comparison view that shows current performance against the previous period. Engineering details that made it work:

LRU-cached previous-period stats (50 entries, 10-day TTL) so cohort comparisons stay fast without re-aggregating on every load.
Outlier-aware metrics — for example, dwell-time values are capped at two hours so broken telemetry doesn't poison averages.
Multi-source aggregation in a single coherent view, designed so the ops team can see program health at a glance instead of jumping across six tools.

Auth & Compliance

Custom Next.js middleware enforcing two layers of access control: an email-domain whitelist (only Quantum and Vinarchy domains can sign in at all) and per-route admin-vs-viewer access splits for sensitive surfaces (members, registrations, audit logs).
Audit logging wired through the most sensitive admin actions for downstream compliance review.

Technologies Used

Next.js 15 (App Router) / React 19
TypeScript
Supabase (Postgres, Auth, Edge Functions)
MUI 6 + MUI X DataGrid
Tailwind CSS 4 (where it complemented MUI)
Sanity CMS (rewards catalogue, content)
React Query (TanStack)
Zustand
Resend (transactional email)
Klaviyo (email metrics surfaced in the dashboard)
Turborepo (monorepo)

Why It Matters

Loyalty programs live or die on the operational surface. The consumer app gets the marketing budget, but the admin is where the program is actually run — where members get fixed, orders get reconciled, gamification gets configured, and the team makes the calls that keep retention healthy. Building this surface well, and shipping it in two months, is the kind of work that quietly determines whether a loyalty platform is a success or a maintenance burden.

Technical Implementation

For Quantum agency and Jack Rabbit Wine Club / Vinarchy, we provided:

End-to-end engineering of the admin app — Next.js 15 frontend, API routes, server-side auth middleware
Supabase schema and migration work for the admin-touched models (members, orders, points, rewards, scratch-cards, codes, audit log)
The unified analytics dashboard with LRU-cached cohort comparison and multi-source aggregation
Role-based access control with domain whitelisting and per-route splits
Scratch-card gamification system with prize pools, weighting, and image uploads
Audit logging surface and compliance-grade activity tracking
Integration with Sanity CMS for the rewards catalogue
Integration with Klaviyo for email-program metrics surfaced in the dashboard
