Zenfia
Zenfia represents a complete migration away from restrictive SaaS eCommerce platforms. By building a bespoke headless architecture, we eliminated recurring revenue-share fees while delivering a sub-second shopping experience.
The Operational Bottleneck.
A growing handmade-goods brand had outgrown off-the-shelf platforms. They needed full control over product variants, pricing, inventory and content without paying per-sale platform fees or fighting template limits.
Architectural fragility resulting from manual workflows, unindexed datasets, or third-party template limits.
The Engineering Strategy.
We engineered a bespoke Next.js storefront backed by Convex, with a complete in-house admin panel: products with variants, categories, orders, coupons, a gallery & homepage CMS, role-based team access and live analytics, plus an interactive 3D product viewer and Razorpay checkout.
How the system was constructed.
A serverless Next.js edge deployment communicating with a Convex real-time database via tRPC, ensuring instant UI updates across the admin and storefront.
Frontend
Next.js App Router, Tailwind CSS, Framer Motion for fluid transitions.
3D Engine
React Three Fiber rendering optimized GLTF models for product visualization.
Database & API
Convex providing end-to-end type safety and real-time WebSocket subscriptions.
Payments
Razorpay Webhooks handling async payment capture, refunds, and failures.
Engineering Challenges Overcome.
Variant Combinatorics
Designing a relational database schema in Convex to handle complex product variants (Size, Color, Material) with independent pricing and inventory tracking.
Performance Overhead of 3D
Lazy-loading the WebGL context and compressing 3D models via Draco to ensure the 3D viewer did not impact Core Web Vitals on mobile.
Technology Selected.
Engineered with modular, standards-compliant tooling designed for zero lock-in and high-speed execution.
Production Capabilities Shipped.
Custom admin panel: CRUD + analytics
3D product viewer & galleries
Razorpay checkout, coupons & COD
Real-time inventory & role-based access
Achieved a 100% reduction in platform transaction fees, improved mobile conversion rates via sub-second page loads, and streamlined internal operations with a tailor-made admin dashboard.
