Custom stores for Mumbai brands
Mumbai D2C brands often need more than a theme: a browsing experience that matches the brand, checkout that works well on phones, and an admin panel the team actually likes using. Ferrea Fashion's store, with video-style product browsing, is an example of what that looks like.
Day-to-day work is remote, with a live preview link so you can check progress from anywhere. For kickoff and important reviews, I can come to your office in Mumbai.
