What You’ll Do:

Review and audit the existing React/JS codebase
Identify and fix bugs, race conditions, and unstable logic
Modularize components and improve state management
Implement robust error handling and logging
Optimize performance and ensure reproducibility across environments
Document the workflow clearly for future onboarding and handoff
Requirements:

3+ years of experience with React and JavaScript

Strong debugging and diagnostic skills
Experience with modular architecture and reusable components
Ability to write clean, teachable code with clear comments and structure

Bonus if you:

Have experience mentoring or refactoring intern-level code
Can suggest improvements to UI/UX for operational clarity
Are comfortable working with symbolic logic or telemetry summaries
Deliverables:

A stable, refactored version of the workflow

Clear documentation and setup instructions
Optional: Suggestions for future enhancements or scalability
