Why AS400/IBMi Development For Your Project?

If there were a Mad Men show for technology, it would be about IBM’s AS/400 systems and RPGLE language. Conceived in the 1950’s, IBM technologies dominated manufacturing

If there were a Mad Men show for technology, it would be about IBM’s AS/400 systems and RPGLE language. Conceived in the 1950’s, IBM technologies dominated manufacturing and information technology to such a degree that almost 30,000 companies still maintain hardware and software related to IBM i Series, AS/400, SMART400 and RPGLE.

While some companies have retired AS/400 and IBM i Series, others retain it, for good reasons. First of all, the work of moving from a legacy system that’s been around since the 1950’s is an upheaval that requires choosing a new platform, installing and implementing new software, then auditing and updating data. The Mad Men of IBM’s AS/400 and the IBM i Series built a system that works like a tank with all of its redundancies, like a Mack truck with its power and performance– CPUs that are 3-5 times more powerful than competitors- as well as like a high speed train. IBM i technology can be scaled, with excellent small starter systems for mid-sized enterprises to powerful large servers and systems for large size enterprises. Plus it supports multiple operating systems.

Chances are, if your company needs IBM i developers, it’s because you trust your system, but you need to integrate ERP, cloud solutions, EDI, API, and frameworks to improve UI. The rub is finding AS/400 RPGLE programmers. The age of the IBM i systems means most of the hotshot developers retired, while younger developers trained in cloud solutions, the latest database management, and ERP/EDI/API/UI technologies.

Our AS/400/IBM iSeries programmers are specially trained professionals to use the RPG programming language to manipulate and solve current systems issues, including cloud computing, database management and development, and hardware solutions.

Our programmers create codes that can be integrated into business operations in order to ensure a higher level of efficiency. On any particular day, our RPG programmers generate new code, maintain and update existing code programs and help you with analysis, design, development and maintenance of your IBMi systems. Our programmers work with RPG, RPG ILE, RPG-FREE, and SQL. They are experts in JD Edwards Cloud solutions, EDI integration, Prism ERP, and Smart400 for fintech, B2B operations, e-commerce, and more.

Our developers draw from a wide variety of tools and technological expertise. They follow functional specifications in order to create technical documentation and develop pseudo codes, strengthen your existing code or troubleshoot your business processes to diagnose where the issues are. They will help your enterprise modernize legacy code, integrate your ERP or EDI solutions, as well as develop and maintain applications. If you need support for existing software, they can help debug, locate and solve issues.
