About the technology
IBM i in practice
IBM i is the operating system and application stack many companies still run on IBM Power hardware. It is used for core business workloads that need stability, strong database integration, and controlled change. People also know it as AS/400 or iSeries in older systems and conversations.
What specialists do
- Maintain and extend RPG and COBOL applications
- Work with Db2 for i data and batch jobs
- Build interfaces to web services, ERP, and file flows
- Support modernization from legacy screens to cleaner integrations
Strong IBM i specialists keep daily operations safe while making targeted improvements. They understand how applications, data, and system objects fit together on the same platform.
Ecosystem and tooling
IBM i work often touches CL, SQL, Db2 for i, and IBM Navigator for i. Depending on the setup, specialists also use modern IDEs, source control, and integration tools for APIs, messaging, and deployment steps. Good experts know both the older operations style and the newer ways to automate it.
When companies bring help
- A critical application is hard to change
- Skills for RPG, CL, or COBOL are thin
- An upgrade or migration is due
- Integrations with newer systems are overdue
In Hamburg, this often matters for logistics, trade, finance, and industrial companies that still depend on stable back-office processing. Freelance support works well for projects that need focused expertise without a long hiring cycle.
What strong professionals look like
A strong IBM i professional reads legacy code, understands data dependencies, and documents changes clearly. They test carefully, respect release windows, and know when to modernize and when to leave stable parts alone. They also explain trade-offs in plain language for mixed technical and business teams.
Modernization focus
IBM i projects are rarely only about maintenance. They may include API layers, reporting changes, security hardening, or gradual migration to newer interfaces while keeping core functions intact. The best specialists reduce risk first, then improve structure step by step.
Frequently asked questions
What clients ask us most about IBM i — answered in short.
IBM i is used for core business processing that needs reliability and tight data handling. Many companies run order processing, inventory, finance, and back-office workflows on it. It is especially common where the application and database have grown together over time.
IBM i is the modern name for the operating system on IBM Power hardware. AS/400 and iSeries are older platform names that many people still use when searching or speaking about the same environment. In practice, specialists often need to understand all three terms.
A strong IBM i specialist usually works with RPG, CL, SQL, and Db2 for i. In many projects, that also includes interface work, batch scheduling, security settings, and source control. For modernization, API design and integration knowledge are often important too.
It depends on the task, but IBM i work usually benefits from someone who has already handled production systems. Simple maintenance can be done by a focused specialist, while a migration or restructuring needs deeper platform knowledge. If old code and business logic are tightly linked, experience matters more than speed.
Bring in IBM i help when a system is stable but hard to change, or when the team needs short-term depth for a release, migration, or audit. Freelance specialists are also useful when internal staff know the business well but lack current platform experience. That mix is common on long-lived systems.
IBM i is different from many open systems because application, database, and system management are closely integrated. That can reduce operational friction, but it also means the skill set is more specific. Companies often keep IBM i for the core and connect it to newer tools around it.
Yes, many IBM i tasks can be done remotely, such as code changes, analysis, testing, and documentation. On-site time in Hamburg can still help during sensitive cutovers, user workshops, or access-restricted environments. The right setup depends on system access and the change window.
Look for a IBM i specialist who can explain how the program flow, data model, and operations fit together. Good signs are clear change notes, careful testing, and practical suggestions that fit the existing system. Ask for examples of maintenance, integration, or modernization work, not just broad platform knowledge.
