• Identifying requirements for micro frontends: Collaborate with business stakeholders to determine the necessary functional and non-functional requirements for each micro frontend component and required services.
• Documenting requirements for micro frontends: Create detailed documentation for each
  identified micro frontend, including functional descriptions, expected behaviours, and
  dependencies.
• Designing micro frontend solutions: Assist the architecture team in designing the architecture of
  the micro frontends, including integration with backend services (microservices architecture),
  APIs (SAO architecture), and databases.
• Creation and maintenance of documentation: Ensure that documentation is created for every
  micro frontend, including design, API specifications, deployment guidelines, and scalability
  considerations. This documentation will be updated throughout the project lifecycle.
• Identifying risks and issues: Proactively identify potential risks related to micro frontend
  solutions, integration, performance, scalability, and security, document them and work on mitigation strategies.
• Creating a list of micro frontends: Define which parts of the monolithic frontend should be
  converted into independent micro frontends.
• Breaking down development tasks: Prioritize and allocate development tasks for the creation of
  micro frontends, ensuring they align with business needs.
• Identifying shared data: Ensure that the frontend is designed to work with shared data, while
  maintaining separation between microservices.
• Creating documentation: Prepare or support the preparation of HLA, HLD and development of
  LLD Documentation, or equivalent Agile documentation (e.g., user stories) following client's
  templates.
• Analyzing current performance: Use performance measurement tools to assess the performance
  of the current monolithic application.
• Identifying optimization opportunities: Examine the codebase, network requests, and server
  usage to identify bottlenecks. Collaborate with backend teams to address potential server-side
  performance issues.
• Implementing optimizations: Apply solutions such as lazy loading, caching, code splitting, and
  other techniques to improve performance.
• Testing performance: Conduct pre- and post-optimization tests to measure improvements.
• Ensuring security: Implement security best practices to mitigate performance risks related to
  security issues, such as preventing denial of service (DoS) attacks, ensuring secure APIs, and
  following OWASP TOP 10 standards for secure coding.
• Creating technical documentation: Provide clear and comprehensive documentation on the
  architecture, setup, and usage of micro frontends. 
• Conducting code reviews: Ensure that the development team follows coding standards, best
  practices, and performs adequate testing.
• Continuous feedback: Provide ongoing feedback during code reviews and ensure continuous
  improvement in the code quality.
• Maintaining documentation: Ensure that documentation is maintained throughout the project
  lifecycle.
• Supporting requirement analysis: Assist the business and architecture teams in analyzing
  frontend requirements from a technical perspective.
• Providing UI/UX guidance: Offer suggestions and feedback on UI/UX design and usability-based
  on the technical implementation.
• Ensuring alignment between frontend solutions and business requirements: Support the
  architecture and development teams to ensure the frontend solutions meet business objectives
  while maintaining adherence to technical standards and design patterns.
• Assisting in identifying technical challenges: Work with the development team to identify and
  address any technical challenges that arise during the integration of UI components into the
  frontend.
• Documentation of business requirements: Ensure that the business needs are fully understood
  and translated into functional UI/UX requirements.
• Coordinating with backend developers: Work closely with backend developers to define API
  endpoints and shared data structures.
• Ensuring frontend functionality: Ensure that the frontend receives the necessary data and
  functionality from backend services, displaying it correctly to the end-users.
• Aligning on response format and structure: Align with backend teams on the format and
  structure of service responses to ensure consistency across both frontend and backend.
• Collaborating on integration points: Collaborate with backend teams on integration points to
  ensure smooth and efficient data exchange between frontend and backend.
• Conducting joint testing sessions: Participate in joint testing sessions to validate frontend backend
  integration and address any issues.
