The challenge
Fashion Nova is one of the top 3 stores on Shopify, and in 2025 it passed 100 million orders on the platform. Hundreds of new products go live every week, and traffic spikes with every drop. The mobile app and the storefront both had to keep up with a catalog that never sits still.
The work
A headless React Native app
Sachin built the mobile app on Shopify's Storefront GraphQL API, so products, collections and prices come straight from the store. There's no second catalog to keep in sync.
Search, collections and catalog on Shopify Plus
Sachin led the search, collections and catalog work on Shopify Plus. That's the part of the store that has to absorb hundreds of launches a week.
A faster store and calmer operations
Sachin cut first paint and load time on the storefront. He added alerts on key thresholds, so problems got a response in hours instead of days. He also built internal tools in Vue and Nest.js that cut the inventory team's workload by 30%.
Design and quality
Shruti shipped targeted UX changes alongside the engineering work. Test coverage stayed above 70%, with React Testing Library, Jest and TestCafe on the web and BrowserStack for the mobile app.
The outcome
The storefront got faster, and internal tools cut the inventory team's workload by 30%.
