A CMS (Content Management System) developer designs and implements software systems that allow users to create, manage, and modify digital content on a website without specialized technical knowledge. They work with platforms like WordPress, Joomla, or Drupal, customizing them to meet specific business needs. An ORM (Object-Relational Mapping) developer creates and maintains software that maps data from an object-oriented programming language to a relational database. This allows developers to perform database operations in an object-oriented way, enhancing productivity and code maintainability. They work with tools like Hibernate, Entity Framework, or Sequelize, ensuring efficient data manipulation and retrieval.
