About Our Client

The client is a fast-growing retail startup based in the USA, specializing in trendy fashion and lifestyle products for millennials and Gen Z shoppers. Focused on offering curated collections and exclusive product drops, the company has quickly built a loyal customer base through its social media-driven marketing.

Challenge

The client was relying on a basic Shopify store that limited their ability to customize the shopping experience, scale for flash sales, and integrate with third-party systems. The out-of-the-box platform restricted key functions like dynamic pricing, loyalty program integration, and personalized product recommendations.

Additionally, the client wanted full ownership of the codebase to support long-term growth and future product line expansions. They needed a robust, mobile-first e-commerce solution with seamless backend operations and fast time-to-market for their new online store.

Solution

We collaborated closely with the client to define clear requirements through a series of workshops. Our business analyst identified the critical workflows, while our UX/UI team designed a sleek, mobile-optimized interface focused on effortless navigation, product discovery, and a frictionless checkout process.

Our development team built the custom e-commerce platform using React for the front-end and Node.js with MongoDB for the back-end, ensuring scalability and performance. We implemented:

  • A dynamic product catalog with customizable attributes and pricing
  • Advanced filtering, search, and product recommendations
  • A seamless checkout experience with Stripe integration
  • Logistics automation with ShipStation
  • Customer relationship management (CRM) integration for marketing automation
  • Admin dashboards for inventory, order, and customer management

We also set up a scalable cloud infrastructure on AWS with CI/CD pipelines for smooth deployments.

Results

  • 200% increase in online sales in the first six months
  • 35% rise in mobile conversions
  • Seamless flash sale events with 10,000+ concurrent users handled smoothly
  • 90% reduction in manual backend operations
  • Excellent user feedback on speed and ease of shopping

The new platform enabled the client to take full control of their online business, deliver a superior shopping experience, and scale confidently for future growth.
