Hiring an Active Record developer can be a smart move as they are skilled in simplifying database tasks, reducing the amount of code needed, and speeding up development time. They understand how to map between your database and application models, manage data validation, and perform database operations in an object-oriented fashion. This expertise can result in efficient, maintainable code, better software architecture, and a smooth user experience. Additionally, their knowledge in Ruby on Rails, the framework where Active Record originates, can bring added value to your project.
