JSP (JavaServer Pages) freelancers
JavaServer Pages (JSP) is a server-side technology used for creating dynamic web pages. It allows developers to embed Java code within HTML, XML, or other document types, enabling the creation of interactive and data-driven web applications. JSP simplifies web development by separating the presentation layer (HTML) from the business logic (Java code), making it easier to maintain and update web applications.

When hiring a JSP freelancer, look for demonstrable experience in:
- Strong Java programming skills: JSP is built upon Java, so a solid understanding of Java fundamentals is crucial.
- Experience with JSP frameworks: Familiarity with popular frameworks like Spring MVC or Struts enhances development efficiency.
- Knowledge of servlets and JDBC: Understanding how JSP interacts with servlets and databases is essential for building dynamic web applications.
- Front-end web development skills: Proficiency in HTML, CSS, and JavaScript is often necessary for creating user-friendly interfaces.
- Version control systems: Experience with Git or other version control systems is important for collaborative development.
Main expertise areas
