Client Overview: A high-growth D2C fashion brand was struggling with 10-second page loads and frequent crashes during seasonal sales on their legacy Magento installation. They needed a partner who could modernize their architecture without disrupting ongoing sales.

"The Developers.dev team didn't just fix our site; they re-engineered our business. Our conversion rates on mobile have doubled since the headless migration."
The Challenge
- High server costs due to inefficient code
- Poor mobile UX causing 80% cart abandonment
- Difficulties in updating content across 5 global regions
- Outdated M1 architecture with security risks
The Solution
We implemented a Headless Adobe Commerce solution using PWA Studio for the frontend and a microservices-based integration layer for ERP and CRM sync. Our team migrated over 200,000 SKUs and 1M+ customer records with zero downtime.
Outcomes
- Mobile conversion rate increased by 42%
- Average page load time reduced to 1.8 seconds
- Zero downtime during 5x traffic spikes
