• 5+ years of professional experience in fullstack development, with a focus on both Python backend and modern JavaScript/React frontend frameworks.
• Frontend Expertise:
  Proven mastery of React, including functional components, hooks, and advanced state management (e.g., Redux, Context API). Experience with Type Script is a strong plus.
