What we doServices built for
Services built for
eCommerce growth.
Four focused disciplines. One goal: a store that sells more than it costs to build.
01
Shopify Design
Custom storefronts built around your brand identity. Every pixel crafted for conversion — not just aesthetics. We design for the scroll, the tap, and the checkout.
Custom UIMobile-firstBrand systems
02
Shopify Development
Liquid, React, and Hydrogen builds that load fast and scale hard. From theme customization to headless commerce — engineered to perform.

03
Store Redesign
Your existing store is leaving money on the table. We audit, redesign, and rebuild with a conversion-first lens — no guesswork.

04
CRO & Optimization
Data-driven testing that finds the friction and removes it. A/B testing, heatmaps, funnel analysis — we optimize until the numbers move.

Why NuxCartWe don't just build stores.
We don't just build stores.
We build revenue machines.
3.2×avg. CVR improvement
Conversion First
Every design decision is tested against one question: does this help someone buy? We optimize for revenue, not awards.
95+avg. Lighthouse score
Built for Performance
Sub-2-second load times on every build. Google Lighthouse 95+. Because a slow store is a losing store.
10×traffic-ready architecture
Designed for Growth
We build with scale in mind. Your store today should handle 10× the traffic tomorrow — without a rebuild.
NuxCart is a boutique Shopify agency founded by engineers and designers who got tired of watching great products fail because of bad stores. We've been building for DTC brands since 2019 — and we only take on work we're confident we can move the needle on.
How we workFrom brief to live
From brief to live
in four steps.
A disciplined process that eliminates surprises and ships on time.
Phase I
Discover
We audit your current store, understand your brand, and map your customer journey. We find the revenue leaks before writing a single line of code.
DeliverableAudit report + strategy brief
Phase II
Design
High-fidelity Figma designs built around your brand and optimized for conversion. You see it before we build it — every screen, every state.
DeliverableFull Figma prototype + design system
Phase III
Develop
Pixel-perfect Shopify builds in Liquid or Hydrogen. Integrated with your stack — Klaviyo, Recharge, Gorgias, whatever you run on.
DeliverableFully built + tested Shopify store
Phase IV
Launch & Optimize
We don't disappear at launch. 30-day post-launch monitoring, A/B testing setup, and CRO iterations until the numbers move.

Client results
Don't take our word for it.
“NuxCart rebuilt our store from scratch. Within 60 days of launch, our conversion rate went from 1.2% to 3.8%. That's not a redesign — that's a revenue transformation.”

Founder, Luminos Skincare
“We'd worked with three agencies before NuxCart. The difference is they actually understand Shopify — not just design. They think in conversions, not just pixels.”

“Fast, communicative, and they ship what they promise. Our Hydrogen build went live two weeks ahead of schedule. First month revenue hit $140K — we'd never seen numbers like that.”
