About Front-End Development

Front-end development focuses on the client side of websites and web apps. It covers designing, coding, and implementing visual layouts. Front-end engineers usually work with UI/UX designers who create the appearance of your solution. Front-end development services should also consider SEO requirements, especially when you build a front-end based on SPA technologies, such as React, Vue.js, or Angular. Building a responsive front-end requires optimizing it to the screen sizes of mobile, desktop, and tablet devices.

Front-end developers typically receive wireframes, fonts, design elements, and animations from UI/UX designers. Their primary responsibility is to implement these elements, constructing the aspects of the software that users directly interact with. This includes everything a visitor sees and experiences. Our front-end engineers have a deep understanding of design principles. This means they can meet design requirements accurately and create pixel-perfect layouts. They also have a basic understanding of back-end development. This facilitates effective collaboration with back-end engineers.

Front-end and back-end engineers work with each other. They exchange information to determine the relations between the front end and back end. This process involves deciding which tasks will be handled on each side of the development. Also, our front-end developers are equipped with basic knowledge of back-end development. This enhances their ability to work effectively with the back-end team, ensuring a more integrated and efficient development process.

Most projects are built with modern frameworks (React, Vue.js, Angular, and Ext JS). We often use them in conjunction with Next.js or Nuxt.js for creating SSR and SSG. Such a combination helps us achieve higher rankings on Google and other search engines. Our team has unique expertise in integrating these technologies, a sign of our highly experienced engineers.
