Your expertise in HTML, CSS, and JavaScript will be crucial in translating design mockups and wireframes into interactive and responsive interfaces that delight users on all platforms.

Key Responsibilities:


  • UI Development: Develop intuitive and visually appealing user interfaces for both mobile and web platforms using HTML5, CSS3, and JavaScript frameworks/libraries.
  • Responsive Design: Implement responsive design principles to ensure optimal user experiences across a wide range of devices and screen sizes, including smartphones, tablets, and desktops.

  • Collaboration: Collaborate with designers to understand design requirements and translate them into functional front-end code. Work closely with back-end developers to integrate front-end components with server-side logic and APIs.
  • Optimization: Optimize mobile and web applications for performance, speed, and scalability, employing techniques such as lazy loading, image optimization, and code minification.
  • Testing and Debugging: Conduct thorough testing of front-end components to identify and fix bugs, ensuring high-quality and bug-free code. Utilize debugging tools and techniques to troubleshoot issues efficiently.
  • Accessibility: Ensure accessibility standards are met by implementing features such as proper semantic markup, ARIA roles, and keyboard navigation, making applications accessible to users with disabilities.
  • Version Control: Utilize version control systems like Git, Azure DevOps to manage codebase, and Jira to track changes, and collaborate effectively with team members.
  • Testing and Debugging: Conduct thorough testing of front-end components to identify and resolve bugs and issues. Utilize debugging tools and techniques to ensure high-quality, bug-free code.
  • Mobile Development: Leverage mobile development frameworks/libraries (e.g., React Native, or hybrid frameworks like Capacitor) to build native or cross-platform mobile applications with excellent performance and user experience.


Requirements:

  • Proficiency in HTML5, CSS3, and JavaScript, with experience in modern front-end frameworks/libraries (e.g., React, Angular, Vue.js).
  • Familiarity with mobile development frameworks/libraries (e.g., React Native, Flutter) and mobile platform-specific considerations.
  • Experience with responsive design principles and frameworks (e.g., Bootstrap, Material Design).
  • Knowledge of cross-browser compatibility issues and strategies to address them.
  • Strong understanding of mobile-first and progressive enhancement approaches.
  • Experience with version control systems, especially Git.
  • Solid problem-solving skills and attention to detail.
  • Excellent communication and collaboration abilities.
  • Bachelor’s degree in Computer Science, Engineering, or a related field (preferred).
  • Portfolio showcasing mobile and web front-end development projects is a plus.


Preferred Qualifications:

  • Experience with server-side programming languages and frameworks (e.g., Node.js, Express.js) for full-stack development.
  • Understanding of web security principles and best practices.
  • Familiarity with RESTful APIs and asynchronous request handling.
  • Knowledge of mobile app performance optimization techniques.
  • Experience with mobile-specific features like push notifications, geolocation, and offline storage.
  • Familiarity with testing frameworks/libraries (e.g., Jest, Mocha, XCTest) and test-driven development (TDD) methodologies.
  • Developing User Interfaces: Write clean, efficient, and maintainable code to implement responsive and intuitive user interfaces based on provided designs and specifications.
  • Continuous Learning: Stay updated with latest trends, technologies, and best practices in front-end development. Continuously improve skills and knowledge through self-learning and participation in relevant training programs or conferences.
