Client's Testimonial

"The move to headless was a massive undertaking, and the Developers.dev team was the perfect partner. Their Node.js engineers are true experts in building high-performance APIs. Our site speed is now in the top 1% of the industry, and our marketing team can finally operate at the speed they want to. The impact on our bottom line was immediate and significant."

Jessica Lee, Head of E-commerce

Client Overview

A leading Australian retail brand with over $100M in annual online revenue. Their traditional, monolithic e-commerce platform (Magento) was slow, difficult to update, and provided a poor mobile experience. They wanted to move to a modern, headless architecture to improve site performance, enable omnichannel experiences, and accelerate their marketing team's ability to launch new campaigns.

Problem

The client's website had an average page load time of over 6 seconds, leading to a high bounce rate and a mobile conversion rate that was 50% lower than desktop. The tightly coupled front-end and back-end meant that even small content changes required developer intervention and a lengthy deployment process.

Key Challenges

Poor Performance:

The slow site speed was directly impacting SEO rankings and sales.

Lack of Agility:

The marketing team was unable to quickly launch new landing pages or A/B tests.

Omnichannel Gap:

They couldn't easily extend their e-commerce experience to new channels like mobile apps or in-store kiosks.

High Maintenance Costs:

The aging monolithic platform was becoming increasingly expensive to maintain and scale.

Custom Car Sharing Solution on Google Cloud

Our Solution

We provided a cross-functional "Headless Commerce Pod" that included Node.js back-end developers, a React front-end specialist, and a cloud solutions expert. We architected a MACH (Microservices, API-first, Cloud-native, Headless) solution.

💻 API-First Back-End:

We used Node.js and Express.js to build a robust set of GraphQL APIs that would serve as the single source of truth for all product, inventory, and customer data.

🌐 Decoupled Front-End:

A new, lightning-fast front-end was built using React and Next.js, which consumed data from the Node.js APIs.

☁️ Cloud-Native Infrastructure:

The entire solution was deployed on Google Cloud Platform (GCP), using Kubernetes for container orchestration to ensure high availability and auto-scaling.

✍️ Headless CMS Integration:

We integrated Contentful as a headless CMS, allowing the marketing team to manage content independently of the development team.

Implementation and Execution

API Layer Development:

The project was executed in three main phases: API development, front-end development, and data migration.

PWA Frontend Build:

We used a strangler pattern to gradually migrate traffic from the old Magento site to the new headless solution, minimizing risk.

Cloud Deployment:

Our team worked closely with the client's in-house marketing and design teams in a highly collaborative process.

Integration Refinement:

We implemented a comprehensive automated testing suite using Cypress for end-to-end testing of the user journey.

Load Testing:

The new platform was launched in just under eight months, with a seamless transition for customers.

Phased Rollout:

Post-launch, we provided a dedicated support team to monitor performance and address any issues.

Positive Outcome

🚀 25% Increase in Conversion Rate:

The dramatic improvement in site speed and user experience led to a significant uplift in sales.

⚡ Sub-1-Second Load Times:

The average page load time dropped from 6 seconds to under 1 second.

📈 Marketing Agility:

The marketing team can now build and launch new campaign pages in hours instead of weeks.

📱 Omnichannel Ready:

The client launched a new mobile app powered by the same Node.js APIs just three months after the website went live.
