Hiring a BDD (Behavior-Driven Development) developer is beneficial as they focus on business behavior rather than just technical aspects. They ensure the software developed aligns with business goals and user requirements. Their approach improves communication between tech and non-tech teams, reducing misunderstandings. BDD developers also facilitate efficient troubleshooting with their detailed specifications, minimizing time spent on defects. Their expertise leads to robust, high-quality software that fulfills its intended purpose effectively.
