We’re building a production-grade reviews and ratings system for e-commerce stores, delivered as an app that runs on an e-commerce platform + an external backend. The goal is to let merchants collect verified reviews, moderate them, and display star ratings + reviews on product pages and listings—reliably and at scale. What you will build 1) Platform Integration • OAuth install/connect flow • Required scopes/permissions (products + orders + webhooks/events) • Webhook/event handler for: • product create/update/delete • order status updates (delivered/fulfilled) • Secure token storage + revocation support 2) Core Reviews System (Backend) • Products sync + mapping (handle URL changes safely) • Reviews model: • product review + store review • rating (1–5), text, optional media • “verified purchase” badge (order match) • status workflow: pending/approved/rejected • Moderation tools: • approve/reject, bulk actions, tags • merchant public replies • audit log 3) Review Request Automation • Trigger review requests after delivery/fulfillment + configurable delay • Email templates + localization (Arabic/English) • Tokenized unique review links per order/customer • Basic deliverability setup (provider integration) 4) Storefront Widgets • Star rating badge (PDP + product cards/listings) • Reviews section on product page • Optional store rating widget • Async loading, fast performance, RTL support, no checkout impact • Simple installation method aligned with platform app requirements 5) Dashboard (Merchant Admin) • Setup/status page (connected, sync, webhooks health) • Reviews inbox + moderation • Widget settings (toggle, placement options) • Analytics (reviews volume, request performance, widget impressions/clicks) Tech expectations • Strong full-stack skills: Node.js (Nest/Express) or Python, PostgreSQL, queues (Redis/BullMQ or similar) • Frontend: React/[login to view URL] (or equivalent) • Experience with OAuth, webhooks, background jobs, multi-tenant SaaS • Media upload + storage (S3 or equivalent), image optimization • Production readiness: logging, retries, rate limiting, basic monitoring Deliverables • Working app end-to-end in production environment • Source code + deployment docs • API documentation (OpenAPI preferred) • Test coverage for critical paths (auth/webhooks/review submission) • Admin demo account + merchant install guide Required experience (please include) • 2–3 examples of similar work (apps, integrations, SaaS dashboards) • Experience with e-commerce platform integrations (OAuth + webhooks) • Evidence of shipping production systems (not prototypes)

Hello, I will deliver a production-grade reviews and ratings system that sits on your e-commerce platform and an external backend, with secure OAuth install, scalable product sync, and a robust moderation workflow. I understand you want verified reviews, a status flow (pending/approved/rejected), merchant replies, and audit logs, plus automated review requests in Arabic and English, with localized emails and tokenized links. I will also build storefront widgets (PDP and cards) with star ratings, a reviews section, optional store rating, all loading asynchronously to avoid any checkout impact, and complete RTL support. The admin dashboard will show setup health, inbound reviews, moderation, and analytics. The tech approach uses a secure multi-tenant backend (Node.js or Python), PostgreSQL, Redis for queues, S3 for media, with webhooks for product and order events and robust logging and retries. Deliverables include production-ready code, deployment docs, API docs, and test coverage for key paths, plus a merchant demo account and install guide. Which ecommerce platform(s) do you plan to support initially (Shopify, Shopify Plus, etc.) and any others? How will you handle multi-tenant data isolation and per-merchant configuration? What are your SLAs for moderation actions, webhook retries, and error handling? Which email deliverability provider do you prefer, and what localization specifics should we cover (Arabic/English), including compliance needs? What are the key metrics

Hi I can build this as a production-grade, multi-tenant reviews platform with a secure e-commerce app integration, a resilient backend, and storefront widgets that load fast and don’t touch checkout. The biggest technical risk is data integrity at scale - product URL/ID changes, webhook gaps, duplicate events, and “verified purchase” matching - so I’ll implement idempotent webhook handlers, a durable product mapping layer, and background reconciliation jobs. I’ll deliver OAuth install/connect, encrypted token storage with instant revocation, and event handling for products + orders/fulfillment, with proper retries, logging, and rate limiting. Backend will include full review lifecycle (pending/approved/rejected), media uploads to S3 with optimization, merchant replies, bulk moderation, and an audit log. Review requests will be automated post-delivery with configurable delays, tokenized unique links, Arabic/English templates, and a deliverability-ready provider integration. Storefront widgets (PDP + listings + optional store rating) will be async, RTL-capable, configurable from the dashboard, and designed for minimal performance impact. You’ll get deployable source, OpenAPI docs, critical-path tests, a demo admin, and a clear merchant install guide for production rollout. Thanks, Hercules
