Client Profile
Industry: UK B2B Industrial Equipment Supplier
Tech Stack: Custom Shopify & Headless Integration
Target Audience: Enterprise procurement teams across the UK
The Challenge
The client’s legacy web platform suffered from severe bloat, slow page load times (4.8 seconds on mobile), and high checkout abandonment rates. Their off-the-shelf setup couldn’t handle complex API synchronizations with their warehouse management system, leading to stock discrepancies and lost sales during high-traffic periods.
The CortexZ Solution
CortexZ executed a full-spectrum bespoke web development overhaul:
Intuitive UI/UX layouts structured to guide high-intent prospects directly toward sales actions.
Transparent project delivery with clean, scalable, and completely documented architectures.
Stop leaving high-value market share to your competitors. Partner with CortexZ to establish a steady, reliable stream of inbound leads and organic search growth.
Early technical decisions compound over time. Legacy monoliths create performance bottlenecks, increase maintenance costs, and limit operational agility. As a custom web development company, CortexZ engineers modular, cloud-native web applications built to handle heavy data processing and high concurrent traffic without downtime.
We eliminate technical debt using clean code paths, automated CI/CD pipelines, and isolated microservices across AWS, Google Cloud, and Azure.
Microservices Architecture: Decoupled modules for independent updates, rapid feature deployments, and zero system downtime.
Automated CI/CD Pipelines: Continuous integration and testing workflows ensuring stable, bug-free production launches.
Resilient Cloud Scaling: Auto-scaling server setups that dynamically adjust resources during sudden traffic surges.
Managing multi-author publishing hubs requires a platform that is secure, fast, and easy to operate. As a WordPress web development company, CortexZ engineers custom themes and headless setups that eliminate plugin bloat, harden security, and deliver sub-second page loads.
“The CortexZ Difference: Custom Gutenberg block frameworks and lightweight backends empower your team to launch rich landing pages instantly without compromising performance.”
