1. Bachelor’s Degree or higher in Computer Science or a related field
2. Strong knowledge of HTML, CSS, Vanilla (plain) and JavaScript, including ES 2016/2017/Next: these programming languages are used by front-end developers to create the layout, visual design, and interactive elements of a website or web application.
3. Understanding of web design principles: A good front-end developer should have a solid understanding of design principles such as layout, typography, color theory, and user experience (UX).
4. Experience with front-end development frameworks and libraries: Familiarity with popular front-end development frameworks and libraries, such as React, Angular, or Vue.js is highly desirable.
5. Familiarity with browser development tools: A front-end developer should be familiar with browser development tools, such as Chrome DevTools, which can be used to debug and optimize the performance of a website or web application.
6. Knowledge of responsive design: A front-end developer should be familiar with responsive design principles and techniques to ensure that a website or web application looks and functions properly on a variety of devices and screen sizes.
7. Strong problem-solving skills: Because front-end development often requires finding creative solutions to complex problems, strong problem-solving skills are essential.
8. Strong communication skills: A front-end developer must be able to effectively communicate with other members of the development team as well as non-technical stakeholders such as designers and project managers.
9. Strong attention to detail: Front-end developers must pay close attention to detail in order to ensure that the user interface is visually appealing, easy to navigate, and error-free.
10. Continuous learning: Because the field of web development is constantly evolving, a front-end developer must be willing and able to learn new technologies and techniques on a regular basis.
11. Strong portfolio: Being a successful front-end developer requires a strong portfolio that showcases previous projects and demonstrates an understanding of front-end development principles.

A front-end developer’s primary goal is to make the website or application look good while also making it easy and efficient to use for end users.

Depending on the company’s structure and the project’s requirements, a front-end developer collaborates with different departments and roles within the company to achieve that goal.

A front-end developer typically works with several other team members, including:

• Back-end developers: Front-end developers work closely with back-end developers to integrate the front-end and back-end functionality. They ensure that the user interface they design effectively communicates with the back-end and that data is displayed correctly.
• UX/UI designers: Front-end developers may work with UX/UI designers to create user interface wireframes and mockups. These designs are then used to create the final user interface in HTML, CSS, and JavaScript.
• Project managers: Front-end developers may work with project managers to prioritize tasks, set deadlines, and keep the project on track.
• Quality assurance (QA) engineers: Front-end developers may work with QA engineers to ensure that the website or application is fully functional, and meets user needs.
• Product managers: Front-end developers work with product managers to understand the goals and needs of the project, and to ensure that the final product meets those goals.

Front-end developers: Front-end developers are in charge of implementing the user interface (UI) of an app or website based on pre-designed wireframes and Photoshop files. Front-end developers use their engineering skills to improve performance, fix bugs, and add new features to existing websites, software, and apps. They are equally responsible for building the UI of an entirely new product or platform.  

UI/ UX developers: UI/UX developers are more concerned with delivering a set of assets such as buttons, tooltips, and other modular pieces that are required for front-end developers, so UI takes care of the interaction between users and computer software, whereas UX takes care of the common user experience linked with product or service brands. The UI/UX developer is responsible for creating a visual interface with specific tools and no code, using a set of icons, buttons, colors, and visual elements to improve the user experience.

Back-end developers: Front-end development focuses on the visual elements of a website or app that a user interacts with (the client side). Back-end development, on the other hand, focuses on the side of a website that users cannot see (the server side). They work together to create a dynamic website that allows users to make purchases, use contact forms, and engage in any other interactive activities while browsing a website.

Front-end developers may face a variety of challenges in their role, including:

• Keeping up with the ever-evolving web development technologies and trends: The web development industry is constantly changing, with new technologies and frameworks being introduced on a regular basis. Front-end developers must keep up with these changes and learn how to use them effectively in order to provide better user experiences.
• Cross-browser compatibility: Because different browsers use different rendering engines, web pages may display differently. Front-end developers must ensure that their code is compatible with multiple browsers and devices, and that the website or application looks and works properly on all of them.
• Optimizing website or application performance: Front-end developers must ensure that their code is optimized for performance, so that the website or application loads quickly and smoothly for users. This includes shortening page load times, shrinking image and video file sizes, and reducing the number of HTTP requests.
• Creating accessible and responsive designs: Front-end developers must ensure that their designs are accessible by all users, including those with disabilities. They must also make sure that their designs are responsive, enabling them to adapt to different screen sizes and devices.
• Troubleshooting and debugging: Front-end developers must be able to troubleshoot and debug issues that arise during development, often working closely with back-end developers to identify and fix the issue.

Overall, the job of a front-end developer requires a solid understanding of web development technologies, design principles, and user experience, as well as the ability to adapt to new technologies and trends.

Additionally, it requires the ability to work in a fast-paced environment, troubleshoot and debug issues, and pay attention to detail

OKRs (Objectives and Key Results) are a framework used to set and track goals within an organization. Here are some examples of OKRs that a front-end developer might set:
