E-commerce Rebuild on Shopify Plus for D2C Brand

The client, a premium D2C lifestyle brand doing $15M in annual revenue, was losing mobile customers at an alarming rate. Their existing Shopify store (built with a heavily customized theme) scored 28 on Google Lighthouse, had a 6.5-second mobile load time, and a mobile conversion rate of just 0.8% — compared to the industry average of 2.1%.

With 73% of their traffic coming from mobile and Instagram, every fraction of a second mattered. They'd received quotes of $300K+ from US agencies for a headless rebuild. They needed a team that could deliver a performant, visually stunning storefront at a fraction of that cost.

We assembled a 4-member frontend-heavy team: 2 Hydrogen/Remix developers, 1 Shopify Plus backend specialist, and 1 performance-focused QA engineer. The team worked in 2-week sprints with daily standups during PST overlap.

Key technical decisions:

**Hydrogen + Remix:** We chose Shopify's Hydrogen framework (built on Remix) for its server-side rendering capabilities and streaming architecture. This gave us sub-second Time to First Byte (TTFB) and progressive content loading.

**GraphQL Storefront API:** Direct integration with Shopify's Storefront API for real-time inventory, pricing, and product data. Custom GraphQL fragments for optimal query performance.

**Tailwind CSS + Framer Motion:** Utility-first CSS eliminated render-blocking stylesheets, while Framer Motion added buttery-smooth micro-interactions that enhanced the premium brand experience.

**Aggressive Performance Budget:** We set hard limits — under 200KB initial JavaScript, sub-2s Largest Contentful Paint, 0 Cumulative Layout Shift. Every PR was gated by automated Lighthouse CI checks.

The new storefront launched 3 days ahead of schedule, just in time for Black Friday.

Lighthouse scores jumped from 28 to 97. Mobile load time dropped from 6.5s to 1.8s. Mobile conversion rate climbed from 0.8% to 2.3% — a 187% increase. In Q1 after launch, the brand reported $1.2M in additional revenue attributed directly to the improved mobile experience.

The project was completed for under $80K — less than 30% of the US agency quotes. The client has since expanded the engagement to include a custom loyalty program and subscription commerce features.
