Job Description

  • Lead the evolution of the platform's architecture, ensuring scalability and maintainability.

  • Maintain and modernize the React-based frontend and Node.js/PHP backend.

  • Enhance REST APIs focusing on security, flexibility, and performance.

  • Optimize workflows, automation, and tooling for better developer experience (DX).

  • Implement performance improvements such as lazy loading, caching, and server-side rendering (SSR).

  • Improve database query performance and reduce backend bottlenecks.
