Project Phoenix
Project "Phoenix" was a large-scale legacy modernization project for a major regional retailer. We successfully executed a phased replacement of their slow, monolithic platform with a high-performance, headless architecture using the Strangler Fig pattern, all with zero downtime.
The Challenge
The client was losing market share due to an aging, tangled "monolith" platform. It was slow, unstable during sales events, and hindered feature development. They needed to modernize to survive but could not afford the business disruption of a "big bang" rewrite.
Our Solution
We implemented the "Phoenix Pattern" (Strangler Fig). We completely decoupled the frontend using Next.js for a lightning-fast storefront. The backend was rebuilt as independent Java microservices. An API Gateway acted as a facade, routing traffic between the old and new systems, allowing us to replace the monolith piece by piece (Catalog, Checkout, etc.) without downtime.
