High-Performance Restaurant Info Web Platform

I’m reaching out to request a proposal for building a mobile-first, high-performance web platform that displays restaurant information (menus/prices/offers) with a multi-role authentication system and multiple dashboards . I’m intentionally keeping this email focused on what needs to be built technically, without going too deep into the product story.

1) Scope of Work (Modules)
A) Public Web App (User-Facing)

* A fast, mobile-first responsive web app optimized primarily for smartphones.
* Restaurant discovery UI (both list and map views), restaurant profile page, and full menu display.
* User accounts:

* Sign up / sign in
* Optional social login (e.g., Google OAuth) if feasible.
* Core features on the public side:

* Search + basic filters
* Browsing history (recently viewed restaurants)
* Favorites/bookmarks
* Offers page
* “Report / Feedback” submission (e.g., incorrect menu item name/photo/price) creating a ticket for review.

B) Admin Dashboard (For Platform Management – Us)

* Separate, secure admin login (Super Admin / Admin).
* Full restaurant and content management:

* Add/edit/delete restaurants
* Restaurant status management (supported/unsupported, verified/unverified)
* Manage user reports/tickets and moderation flows
* Manage content like offers/coupons as needed.
* Role-based access control (RBAC) for internal team roles (Admin / Support / Moderator, etc.).

C) Restaurant Owner Dashboard (For Verified Restaurants)

* Separate login for verified restaurant owners/managers.
* Allow restaurant managers to update:

* Menus, prices, offers, buffet details (if applicable)
* Core profile info (hours, contacts, social links, etc.)
* Restaurant verification workflow (claim/verification):

* Owner submits verification request → manual review by admin → approve/reject.

2) Non-Functional Requirements (Performance, Scalability, UX)

The #1 priority is speed and responsiveness with minimal loading screens and an architecture that can scale to millions of users and heavy navigation/activity.

My preferred technical direction (this is the target requirement):

* Frontend: Next.js (React) + TypeScript , using SSR/SSG/ISR depending on page needs.
* Backend: NestJS (Node.js) + TypeScript (or an equivalent high-performance service layer such as Go for critical services), exposing a clean API (REST or GraphQL).
* Database: PostgreSQL (optionally PostGIS for geo/nearby queries) + Redis for caching / or / MySQL no problems.
* Caching & CDN: CDN (e.g., Cloudflare) + aggressive caching strategy for API and pages, optimized image pipeline (WebP/AVIF), lazy loading, compression.
* Architecture: Service-based layering, strong RBAC, rate limiting, logging/monitoring (observability).
* Maps optimization: Google Maps integration (or alternative) with marker clustering and progressive loading of nearby restaurants.
* Mobile-first UX: Fast tap interactions, clean UI for “in-car” usage, minimal heavy animations.

Expected outcome: a very fast web platform built for scale, with a clean foundation that can later support a mobile app without a full rewrite.

3) What I Need From Your Proposal

Please include:

* Your recommended stack/architecture aligned with the performance goals .
* A phased delivery plan (MVP first, then enhancements).
* Estimated timeline and total cost (and any milestones if applicable).
* Relevant past work (if any).
* What you will deliver in terms of:

* Source code + repo structure
* Testing approach
* Documentation
* Deployment plan (production environment, CI/CD if included)

If this fits your expertise, please send your proposal and we can schedule a short call to confirm technical details and next steps.

Best regards,
