  • Work closely with backend developers to ensure seamless interaction between the frontend and APIs or blockchain nodes for real-time data display.
  • Ensure security best practices are followed, particularly concerning user data and blockchain interactions.
  • Write clean, maintainable, and efficient code using modern JavaScript frameworks (e.g., React, Vue.js, Angular).
  • Conduct regular testing, debugging, and troubleshooting to enhance the performance and usability of the platform.
  • Stay up to date with the latest trends and technologies in DeFi, blockchain, and frontend development to continuously improve the product.
  • Collaborate with cross-functional teams (design, backend, product) to deliver new features and improvements according to the product roadmap.
  • Contribute to the continuous improvement of development processes and workflows.


Knowledge & Experience


  • Proficiency with modern JavaScript frameworks and libraries (e.g., React, Vue.js, Angular).
  • Strong skills in HTML, CSS, and JavaScript (ES6+), with a focus on responsive design and accessibility.
