What can a front end developer from Sunbytes do for you?

A front end developer is responsible for creating an attractive display and a functional experience for the end-users by working on the “surface” of software programs, websites or html email displays. A front end developer is a person who builds the first look & feel of the website and makes a website easy to manipulate and use. More than that, front end developers also take the key role in adding new functionality to the current software application or enriching the content of a website with new display blocks to make it more useable, accessible, and eye-catching. Everything that the end-user touches, surfs, scrolls are the fruit of the hard work of a front end developer. Specifically, our front end developers can support you with the following tasks:


Develop and maintain user interface

Our front end developers will create an interactive, SEO-friendly interface for your website or application and they will ensure that it is beautiful, functional, and accessible.


Optimize web, fix bugs and test usability

Full-stack developers at Sunbytes are experts in front end testing involved with the test of presentation capability on the website, user experience, and interaction. Our Graphical User Interface Testing (GUI Testing) at Sunbytes will include testing all the elements such as navigation, font type and size, functions of field, colors, and consistency throughout the web interface.


Implement design on websites and applications

If you are not happy with the current design or theme of your website, let our front end developer support you to bring the concepts you have in your mind to life.


Create animated & mobile-friendly content
