Hello, I am Tony Stark. I am digital marketing specialist and freelancer.  The process of establishing and maintaining websites and web applications is referred to as web development. It involves designing, coding, and deploying websites that are functional, visually appealing, and user-friendly. Several skills are crucial for web development. Proficiency in programming languages like HTML, CSS, and JavaScript is essential for front-end development. Back-end development requires knowledge of languages such as Python, PHP, or Ruby, along with database management skills.
