What is an IBM i developer?

An IBM i Developer is a software professional who specializes in developing, maintaining, and modernizing applications on the IBM i platform (formerly known as AS/400 or iSeries). They typically use languages such as RPG, COBOL, and CL, and work with IBM's integrated operating system and database. These developers are responsible for ensuring business applications run smoothly, integrating new technologies, and often upgrading legacy code to meet modern standards.

What are some common challenges faced by IBM i developers when modernizing legacy systems?

IBM i Developers often encounter challenges when updating or integrating legacy applications with newer technologies. These challenges include understanding and refactoring decades-old code, ensuring compatibility with modern web or mobile interfaces, and maintaining data integrity during migrations. Collaborating closely with business analysts and other IT teams is crucial for translating legacy functions into modern solutions while minimizing disruption to daily operations. Staying up to date with modernization tools like RPG IV, SQL, and APIs can greatly aid in overcoming these hurdles.

What are the key skills and qualifications needed to thrive as an IBM i developer, and why are they important?

To thrive as an IBM i Developer, you need a strong background in RPG, COBOL, or CL programming, familiarity with IBM i (AS/400) systems, and typically a degree in computer science or related field. Expertise in using IBM Rational Developer for i, DB2 database management, and experience with legacy application modernization tools are commonly required. Analytical thinking, problem-solving, and effective communication are vital soft skills for collaborating with teams and addressing business requirements. These skills ensure robust application development, system stability, and the ability to adapt legacy systems to evolving organizational needs.
