Overview

NehaNX is a shopping application built around a straightforward path from product discovery to checkout, with filtering that narrows results quickly and an order tracking view that keeps buyers informed after purchase.

The Challenge

E-commerce flows fail on friction — every extra tap between browsing and checkout costs conversions — so the priority was keeping navigation simple and the app fast under a growing product catalog with multiple filter dimensions.

My Role

I developed the application end-to-end, covering product browsing, cart, checkout, payment integration, and order tracking.

Technical Approach

Built advanced search filtering across category, price, and product attributes so users narrow large catalogs quickly.
Implemented cart management with persistent state so items survive app restarts.
Built a secure checkout flow with integrated payment handling and clear order confirmation feedback.
Added order tracking so users can follow a purchase from confirmation through delivery.
Kept navigation shallow — browsing, cart, and checkout stay reachable within a few taps from anywhere in the app.

Technical Challenges & Solutions

Advanced filtering across multiple attributes risked slowing down product list rendering as the catalog grew.

Solution — Applied filters at the query level rather than client-side, keeping list rendering fast regardless of catalog size.

Checkout is the highest-stakes screen in the app — any state loss during payment directly costs a sale.

Solution — Persisted cart and checkout state through the payment flow so interruptions don't force users to rebuild their order.

Technical Architecture

A Flutter e-commerce client with query-level filtering — category, price, attributes — rather than client-side filtering, keeping list rendering fast as the catalog grows. Cart and checkout state persist through the payment flow so interruptions don't force users to rebuild an order.

Outcome

Delivered a performant e-commerce application with working search, cart, checkout, payments, and order tracking built around minimal navigation friction.
