I am a front-end and somewhat backend developer with some basic knowledge in cyber security too. Following are my skills and areas of expertise:
HTML is basically the fundamental and structural language when it comes to designing webpages. I easily am able to design some pretty basic webpages using HTML.
With my knowlegde and experience in CSS, I can easily style some attractive webpages according to your asks.
With JavaScript, you can build complex interactive websites and browser games, and to connect servers to websites and web applications
PHP is an open-source server-side scripting language that many devs use for web development. It is also a general-purpose language that you can use to make lots of projects, including Graphical User Interfaces (GUIs)
With SQL, databases and records within those can be easily managed. This was one of my favourites to learn.
These languages are my first learns. I can easily design some projects and some cool stuffs using these languages. Currently, I am on a project of designing a game engine with C and C++. I am also working on understanding kernel development through C.
