Hello I am Tony Stark. A web programmer needs a strong foundation in HTML, CSS, and JavaScript. They should be proficient in a server-side programming language such as PHP, Python, or Ruby, and be familiar with popular web frameworks such as Django, Laravel, or Ruby on Rails. Additionally, knowledge of SQL, NoSQL databases, and RESTful APIs is essential. Strong problem-solving, debugging, and communication skills are also important for developing a robust and scalable web application.
