The internship presentation summarizes Saikat Chowdhury's internship at Varcons Technologies, a leading technology company. During the internship, Saikat developed a full-stack web application for a yoga training center using HTML, CSS, JavaScript, Python, Django, and SQL. The yoga center website allows users to manage trainer details, member information, classes, and other center activities online. By building the full-stack web application, Saikat gained skills in frontend and backend web development, including using HTML, CSS, JavaScript, responsive design, and basic programming. The yoga center website aims to reduce manual work and allow the center to better manage operations and track details.
