The role of a software architect in IT projects is to define the overall structure and design of software systems. They evaluate technical requirements and establish best practices for coding standards, technology stacks, and architecture patterns. Software architects facilitate communication among stakeholders, ensuring that the project aligns with business goals and technical feasibility. They also anticipate future needs for scalability and maintainability. By laying a strong foundation, software architects help guide development teams, reduce potential risks, and enhance the likelihood of delivering high-quality software solutions.
