What Is Frontend Development?

First thing first, what exactly is frontend development? This is the area of web development with a focus on a website or application's user interface and user experience - what is also known as UI/UX design. Frontend development prioritizes the user experience and aesthetics of a website, as well as creating and maintaining code for the user side of an application. This development technology is in charge of building the visual and interactive aspects that consumers engage with when using a website using a range of computer languages and tech stacks, including HTML, CSS, and JavaScript. It’s important to always remember that frontend development is a critical part of web development, as it shapes how users interact with a website or application and can greatly influence their overall experience.

Why Hire Frontend Developers? 

Frontend developers collaborate on a regular basis with UI/UX designers and other tech stack developers to make sure that the frontend functionality and design meet user demands and the project's overall objectives. These IT professionals are responsible for making sure the website or app is aesthetically pleasing, user-friendly, and responsive no matter the type of platform and screen size. 

Key basic skills of a frontend developer include knowledge of HTML, CSS, and JavaScript, experience with responsive web design, understanding of web standards, and a keen eye for detail. For example, some of their go-to responsibilities where they should put these abilities to work would be creating user interfaces with HTML and CSS, developing interactive elements with JavaScript, and testing webpages across multiple browsers and devices. Moreover, a good frontend developer should have knowledge of cross-browser compatibility issues and an understanding of accessibility requirements.

Frontend developers can work wonders with any application, from eCommerce sales sites and company portfolios to wellness mobile apps or modern habit trackers. Because of this, they’re a highly valuable asset to add to your company’s workforce, and learning how to hire frontend developers should be an absolute priority. Without this type of developer, your applications - whether mobile or desktop - would not be given their best chance to shine and generate a greater return on investment. Luckily, our IT hiring team has spent years interviewing, vetting, and hiring frontend developers from the Latin America software industry and all over the world.
