The position of an iSeries Developer has become greater in importance. These experts have an important role in using the potential of the IBM iSeries system in making sure running smoothly, and supporting company innovation. In this blog, we'll look at the main things of an iSeries Developer, including the skills and expertise important, the many services they might offer, and the problems they may face.

What is an iSeries Developer?

An iSeries Developer is a specialist in using the IBM iSeries platform, which has long been an important part in business computing. This platform, formerly known as AS/400, has gone through changes in order to adapt to the changing technological environment. iSeries Developers design apps and systems that are optimized for this powerful platform.

What Skills and Knowledge Required?

The iSeries development environment requires a unique combination of skills and knowledge. RPG (Report Program Generator) proficiency is necessary as it is still the primary programming language for the iSeries. Also, for database administration and system control, an in-depth understanding of CL (Control Language) and SQL (Structured Query Language) is required.

 iSeries Developers should have a solid understanding of the platform's architecture, including libraries, objects, and the features of the Integrated File System (IFS). As enterprises work to combine iSeries with new technologies, knowledge of modern development frameworks and processes is becoming more and more important.

What Services iSeries Developer can Provide?

An iSeries Developer's responsibilities go above coding. These experts are skilled in designing, developing, and maintaining applications that support important business operations. They work with clients to understand needs and transform them into successful, scalable iSeries solutions.

System integration requires iSeries Developers to provide seamless connectivity between iSeries apps and other parts of the IT ecosystem. Interfacing with online apps, mobile solutions, and other platforms is part of creating an overall and linked IT architecture.

Also, these developers help to manage and optimize existing programs. This includes troubleshooting, performance optimization, and updating the iSeries environment to keep it running at its best.

What are the Challenges of iSeries Developer?

As an iSeries Developer is a rewarding position, it is not without its challenges. One of the most significant barriers is the industry's perception of the iSeries platform as outdated. In a constantly changing technical context, overcoming this misconception and showing the platform's possibilities can be a continuous challenge.

Another difficulty is a shortage of new talent joining the iSeries development space. With an emphasis on developing technologies, the amount of developers with iSeries experience could be limited. This shortage highlights the importance of ongoing learning and upskilling for current iSeries Developers.

Integration with new technology might sometimes be difficult. Adapting older systems to smoothly connect with cloud services, APIs, and other modern aspects needs a strategic strategy as well as an advanced hold of both old and new technology.


An iSeries Developer's work is vast, requiring a combination of conventional skills and the ability to adapt to emerging technology paradigms. These people look after a platform that, regardless of its age, is still an important part of corporate IT infrastructure.

As businesses desire for digital transformation, iSeries Developers' services become highly important. Filling the gap between old systems and new requirements, these individuals play an important role in making sure the iSeries platform's lifespan and relevance in today's IT world.

Although challenges remain, the dedication of iSeries developers in solving them ensures the future survival of the platform. As the digital age advances, iSeries development is expected to remain important, with these developers leading the way to the full potential of IBM's legacy iSeries platform.
