PROBLEMS WE SOLVE

Is slow performance bleeding your revenue?

High-growth e-commerce on React or Next.js? Or stuck on a legacy stack? These problems probably look familiar.

01

Peak traffic crashes

Black Friday hits and your site slows, or crashes entirely. The days that drive most of your revenue become your highest-risk moments.

02

Slow pages, lost sales

Pages take too long to load, costing you conversions with every second. Customers abandon carts. Not because of price, but load time.

03

Failing Core Web Vitals

Your Core Web Vitals are red: LCP, INP, CLS all failing. Google ranks you lower, users bounce faster, and marketing spend converts worse.

04

Large bundles, delayed interactivity

820KB+ of blocking scripts means users click "Add to Cart" and nothing happens. They click again, then leave.

OUR SOLUTION

From dreading peak traffic
to banking on it

Peak seasons should be your biggest paydays, not your biggest headaches. Here's what changes when your infrastructure is built to scale.

OUR APPROACH

How we remove the technical barriers between your traffic and your revenue

The problem changes from project to project. The process doesn't. Expand each step to see what it looks like in practice.

01. Rendering Strategy

open tab

SSR, SSG, ISR, PPR. Matched to each page type. Most teams default to SSR everywhere and watch server costs spike. ISR for product pages, SSR where session data requires it, PPR for personalized content.

02. Caching Architecture

open tab

Edge caching, CDN configuration, cache invalidation. The difference between a 3-second page and a 300ms page is often one misconfigured header. Proper caching shields your backend from traffic spikes.

03. Core Web Vitals

open tab

LCP, INP, CLS diagnosed and fixed at the source. INP is the hardest. It requires architectural change, not optimization. CookUnity: 70% INP improvement after we rebuilt their signup flow.

04. Peak Traffic Infrastructure

open tab

Auto-scaling, load balancing, architecture built for Black Friday. ISR ensures millions of users hit the cache, not your origin server. When 40-70% of annual revenue hits in one week, that matters.

05. Third-Party Scripts

open tab

Tag managers, analytics, A/B tools, personalization engines. A single unoptimized OneTrust banner adds 400KB of blocking JavaScript. We audit every script and load them without blocking the main thread.

06. Conversion Flow Speed

open tab

Checkout, cart, product pages. Optimized for sub-second response. These pages generate the most revenue but are often the slowest. Every 100ms at checkout directly impacts conversion rate.

FAQ on our E-commerce Performance Optimization services

Our checkout is slow, and conversion is dropping – how do we fix it?

Slow checkout is lost revenue at the highest-intent moment. We diagnose the checkout flow with field data, then fix the causes – heavy JavaScript, render-blocking scripts, and rendering strategy – so pages respond fast under load. Performance work like this has delivered 28% more conversions for eCommerce clients.

Our site goes down under traffic spikes – how do we make it reliable?

Fix rendering and caching so most requests are served from cache instead of hammering your origin, and design the architecture to scale under spikes. The goal is a store that stays fast on Black Friday.

Who can fix slow LCP on a Next.js e-commerce store?

We do – slow LCP on a storefront is usually an image, rendering, or third–party–script problem, and we fix it at the source. We diagnose with field data from real shoppers, prioritize the biggest wins, and confirm the improvement in your real metrics. Clients have seen a 70% faster LCP after this work.

Our competitors' sites are much faster than ours – how do we catch up?

Start with a diagnosis of where you're actually losing time, measured on real devices – then fix the causes. Most of the gap is rendering strategy, caching, and third-party bloat. We prioritize by impact, so you close the visible gap first.
