Last position:

Platform Architect & Senior Developer at Direct client, industrial measurement technology, medium-sized company

  • Technical leadership across hardware, firmware, and software teams; scope: hardware/firmware team (4 people) and leadership group (5 people)
  • Consolidated and documented a product family that had grown over more than 15 years and aligned it with CRA compliance — from the bare-metal I/O module to the cloud interface.
  • Provided the most important customer product with the essential requirements and architecture documentation within two months — for a firmware landscape that had grown over more than 15 years. It now supports the customer’s modernization strategy.
  • Established a monthly reporting line to the supervisory board and executive board within three months: nine meetings since 12/2025. The report itself is versioned and built from the CI pipeline; it is based on automatically collected activity and release data instead of assessments.
  • Built a container-based CI/CD infrastructure from scratch: cross-compilation, host tests, and documentation builds in one continuous pipeline.
  • Introduced declarative QA gates for DevOps and development artifacts — from the start using lefthook instead of pre-commit, executed in a dedicated container image.

About the technology

HP-UX in enterprise systems

HP-UX is Hewlett Packard Enterprise’s UNIX operating system for business-critical environments. It runs on HP Integrity systems based on Itanium and on earlier HP 9000 systems using PA-RISC. Companies use it for stable transaction processing, manufacturing operations, telecommunications workloads and long-lived enterprise applications.

Core technologies

HP-UX work often spans the operating system, hardware, storage and application layers. Strong specialists understand the shell, kernel settings, file systems, networking, security controls and service management needed to keep dependent systems reliable.

  • Configure and troubleshoot HP-UX hosts
  • Manage LVM, file systems, storage paths and backups
  • Automate administration with POSIX shell and Perl
  • Support Oracle, SAP and other enterprise workloads

Ecosystem and tooling

The surrounding ecosystem includes HP Integrity and HP 9000 hardware, Serviceguard high availability, Ignite-UX provisioning, and tools for monitoring, patching and backup. Professionals may also work with NFS, LDAP, DNS, TCP/IP, Oracle databases, shell scripts and legacy application frameworks. Knowledge of HPE storage and virtualisation is often useful.

When companies need specialists

Freelance expertise is valuable when internal teams must protect a legacy platform while changing the surrounding estate. Cologne companies in industrial, logistics, financial and telecommunications environments may need local on-site support alongside remote collaboration for maintenance windows and incident response.

  • Diagnose performance, capacity or availability issues
  • Plan patching, upgrades and hardware replacement
  • Move workloads toward Linux or another target platform
  • Document undocumented scripts, interfaces and operating procedures

Migration and continuity

HP-UX projects require more than a server replacement. Specialists assess application dependencies, binary compatibility, database behaviour, batch schedules, network integrations and recovery procedures before recommending a migration or renewal path. They can design parallel operation, validate data flows and reduce disruption during cutover.

A careful professional also distinguishes between PA-RISC and Itanium workloads, checks licensing and support constraints, and preserves operational knowledge that may exist only in scripts or team practice.

What strong professionals bring

The best HP-UX specialists combine hands-on UNIX administration with calm troubleshooting and disciplined change control. They can read legacy shell code, trace problems across hardware and applications, communicate clearly with business owners and produce documentation that another team can use.

For Cologne-based work, German communication may help with on-site operations, while remote projects often rely on clear English documentation and structured handovers. Quality is shown through relevant system evidence, sound recovery planning and an ability to explain technical risk without obscuring it.

Frequently asked questions

Before you brief your next project: the most common questions about HP-UX.

HP-UX is used for long-running enterprise workloads that depend on stable UNIX operations, including databases, ERP systems, manufacturing control and telecommunications applications. It is most common where replacement or migration requires careful dependency analysis and controlled downtime.

HP-UX is closely tied to HPE hardware and its established enterprise tooling, while Linux offers broader hardware choice and a larger current ecosystem. IBM AIX provides a similar proprietary UNIX model on IBM Power systems. The right option depends on application compatibility, support requirements, operational knowledge and migration risk.

A strong HP-UX specialist often brings knowledge of HPE Integrity or HP 9000 hardware, LVM, Serviceguard, Ignite-UX, shell scripting, storage, networking and enterprise databases. Experience with Oracle, SAP, backup systems and Linux migration can be especially useful.

The scope of an HP-UX migration matters more than a generic experience label. A small support task may need focused operational knowledge, while a platform replacement requires someone who can map dependencies, test interfaces, plan rollback and coordinate application, database and infrastructure teams.

Many HP-UX tasks can be performed remotely through secure access, including monitoring, scripting, documentation and migration planning. On-site work in Cologne may still be needed for hardware changes, restricted environments or maintenance windows. German communication can help locally, while English is common in technical documentation.

Bring in an HP-UX freelancer when internal knowledge is limited, a critical incident needs rapid investigation, or a legacy system must be stabilised before migration. External support is also useful for audit preparation, recovery testing, documentation and knowledge transfer.

Ask an HP-UX professional to describe comparable environments, troubleshooting methods and migration decisions without disclosing confidential information. Look for clear reasoning around Serviceguard, storage, backups, application dependencies and rollback. Practical documentation and careful change control are strong quality signals.

Before taking HP-UX work, clarify the hardware generation, operating system release, access model, support status, connected applications and maintenance constraints. Also confirm whether the assignment focuses on daily operations, incident response, migration, scripting or knowledge transfer, since each calls for a different mix of skills.
