Project Overview

A multi-vendor beauty marketplace with reviews at its centre.

Lumina extends a beauty storefront into a marketplace: multiple vendors list products, and customer reviews feed back into ranking and discovery.

The vendor dimension touches everything — product ownership, order routing and the trust signals shown on every card.

The Challenge

Marketplaces live or die on trust. Without review aggregation and clear vendor attribution, buyers cannot tell a good listing from a bad one.

The Approach

Vendor identity and verified review scores were promoted into the core product model, so trust signals render consistently on cards, listings and detail pages.

Core Features

01

Ingredient-aware product model

Each product carries shade, skin-type and ingredient metadata, which powers both filtering and recommendation logic.

02

Recommendation engine

Rule-based matching that suggests complementary products from the current item's category, concern and shade family.

03

Reviews & ratings

Verified review capture with aggregate scoring surfaced on cards, listings and the product detail page.

04

Routine builder

Multi-step routine bundling so customers add a full regimen to the cart in one action instead of item by item.

05

Rich media gallery

Zoomable imagery, swatch previews and lazy-loaded assets tuned to keep the largest contentful paint low.

Architecture & Tech

Tech Stack

React
Engineering Notes
  • React with a component-driven structure, memoised derived state and route-level code splitting to keep interaction snappy.

My Role & Contributions

  • Owned the front-end architecture, component library and state management.
  • Implemented the full React stack for this project.
  • Translated design intent into a responsive, accessible interface across breakpoints.
  • Handled client communication, scope decisions, delivery and handover directly.
  • Deployed and verified the production build.

Delivery Process

  1. 01

    Discovery & scoping

    Requirements distilled into a prioritised scope, user flows and a data model sketch before any code.

  2. 02

    Architecture & design system

    Component hierarchy, state boundaries and a token-based visual system defined so screens could be assembled consistently.

  3. 03

    Implementation

    Built iteratively with React, shipping vertical slices — data, logic and UI together — instead of layer by layer.

  4. 04

    Hardening & launch

    Edge cases, validation, responsive behaviour and performance passes, followed by deployment and post-launch monitoring.

Results & Outcomes

  • Shipped to production and publicly reachable at the live URL.
  • Responsive from small mobile screens through large desktop layouts.
  • Interface patterns reusable across the rest of the product surface.
