Legacy-to-Modern Migration

Risk-free transition from outdated monolithic frontends (jQuery, PHP/Java templates) to a scalable Node.js & Next.js ecosystem.

Legacy Code Migration

Legacy monolithic architectures often combine robust backends with outdated, slow frontend templates. I specialize in separating these layers. By introducing Node.js as a modern rendering environment, we migrate your user interface from synchronous server-side templates (PHP/JSP) to a high-performance, asynchronous Next.js application, keeping your existing backend data secure while unlocking modern UX.

Modernization Strategy

Decoupling the Frontend

We stop using your legacy backend for HTML generation. Instead, we implement a Node.js middleware that fetches data and renders it via Next.js 16, providing instant page loads.

Incremental Migration

Using the 'Strangler Fig' pattern, we replace pages one by one (e.g., Checkout first, then Catalog). You don't need to rewrite the whole system at once; the old and new sites run in parallel.

Solving the Talent Gap

It is hard to find developers for old proprietary template engines. Modernizing to React and TypeScript opens access to a vast talent pool and speeds up feature development.

Technical Debt Elimination

We replace unmaintainable 'spaghetti code' (jQuery/Vanilla JS) with typed, component-based React 19 logic, ensuring stability and easier long-term maintenance.

Migration Roadmap

  1. 1

    Audit - Analyzing legacy dependencies and tight coupling points

  2. 2

    BFF Setup - Deploying Node.js as a Backend-for-Frontend layer

  3. 3

    Component Build - Recreating UI elements in React with modern accessibility standards

  4. 4

    Routing - Configuring Edge Middleware to serve new Next.js pages

  5. 5

    Sunset - Decommissioning the legacy template engine completely
