Introduction

Legacy applications often slow down businesses due to outdated tech stacks and poor scalability. During my 6-month journey at Equip9, I led the revamp of the Admin Dashboard from PHP to React (TypeScript) and Node.js, which resulted in better performance and modern UX.


The Problem with Legacy PHP

  1. Poor maintainability and limited scalability.

  2. Difficult to implement modern UI and multilingual features.

  3. Slow data fetching and page loads.


The Modern Stack Solution

  • Frontend: React.js (TypeScript) with Chakra UI for a clean, responsive UI.

  • Backend: Node.js with Express for faster, scalable API responses.

  • Authentication: JWT-based secure login.

  • Cloud: AWS S3 and Lambda for serverless file storage and automation.


Key Features Delivered

  • Role-based dashboards (Owner, Partner).

  • Invoice generation module.

  • Multilingual JSON support for global users.

  • Search, pagination, and toggle controls.


Lessons Learned

Migrating a legacy system requires modular design, gradual rollout, and clear API contracts. The new stack made the dashboard 40% faster and far easier to maintain.
