Senior Software Developer

My name is Lennart Altenhof. I’m a software architect and IT consultant based in Ulm, helping companies improve their technology and processes in a targeted way – with tailor-made, high-quality solutions instead of off-the-shelf standard software.

I help businesses design their IT structures and software so that they just work – reliably, securely, and perfectly aligned with their workflows.

That can mean, for example:

• Developing custom software for internal processes or customer data
• Building web portals for employees, clients, or project overviews
• Integrating existing systems, devices, or programs
• Automating recurring tasks
• Building or modernizing network and IT infrastructure
• Troubleshooting, performance optimization, or technical consulting

Unlike large software companies, I work directly and without detours with my clients. You’ll have a single point of contact, fast decisions, and solutions that truly fit your business – implemented efficiently, without unnecessary bureaucracy or long approval chains.

I hold a Master’s degree in Software Engineering and have many years of experience in professional IT projects – most recently as a Senior Engineer in technically demanding environments. I place great value on clear communication, a structured approach, and sustainable technical solutions that don’t just work but reduce workload in the long run.

If you’re looking to improve your IT or digitize your processes, let’s have a no-obligation conversation to find out how I can support you – clearly, reliably, and as an equal partner.

Additionally, I am invested in lighting and live visuals. Focus is on EDM festivals/shows/events as well as Worship/christian events. And if it's EDM, well, then being part of a great House/Tech House experience.
