Grailed
Challenge
Grailed needed to scale their marketplace platform to handle rapid growth in users and transactions. The existing Vue.js frontend was experiencing performance issues with large product catalogs, and the checkout flow had a high abandonment rate. They needed to optimize the user experience without disrupting daily operations.
Our Process
Shopify ecommerce work supported marketplace merchandising and product discovery while Vue.js powered complex interactive flows. Migrated critical components to TypeScript for better type safety. Used Vuex for state management across marketplace flows. Implemented virtual scrolling using vue-virtual-scroller for product catalogs. JavaScript handled custom interactions and form validation.
Reviewed the product goals, user paths, and existing technical constraints.
Mapped the core workflows before changing the interface or architecture.
Built the highest-impact screens and features first so stakeholders could test early.
Connected the frontend to real data, APIs, and content systems instead of static mockups.
Checked performance, accessibility, and responsive behavior across key breakpoints.
Prepared the project for launch with clear handoff notes and maintainable code.
Conclusion
The Solution
Optimized product listing pages by implementing virtual scrolling for infinite lists, reducing DOM nodes and improving scroll performance. Refactored the checkout flow to reduce steps and added real-time validation to catch errors before submission. Implemented lazy loading for product images with blur-up placeholders for better perceived performance. Added TypeScript gradually to catch bugs during development.
- A focused implementation plan tied to the client workflow
- Reusable components and data structures that reduce future rework
- Launch-ready pages with project-specific SEO and performance checks
