Custom Buy Box Development for NODI Kids

Overview: I developed the entire product page for NODI Kids on the Instant platform, focusing on creating a fully custom buy box experience without relying on any third-party apps. The goal was to build a modular, dynamic system that enhanced conversion while maintaining native platform performance and styling.

Custom Add-On Color Selector — Integrated color add-ons with dynamic pricing and live image updates. Each add-on appears as a separate line item in the cart and syncs with the variant image on the slideshow.

Custom Variant Picker — Built from scratch for seamless user interaction, supporting variant logic and image state updates.

Custom Add-On for Tracking Handle — Added a toggleable tracking-handle option that updates product totals in real time.

Dynamic Totals Breakdown — Implemented a transparent pricing summary showing base price + accessories subtotal + grand total for full clarity at checkout.

Result: The final build achieved a fully integrated, app-free buy box system that enhances the customer experience, improves add-on visibility, and maintains Instant’s performance standards. Design by https://x.com/0xCharlota
