Core expertise
Software for distributed systems
I have been developing systems in which multiple services, machines or schedulers have to work together for many years. I consider not only individual components, but also resources, interfaces, failure scenarios, deployment and subsequent operation.
My experience ranges from classic client/server and backend systems through microservices to Apache Mesos frameworks and ClusterD, the continuation of the Apache Mesos model that I started and continue to develop.
- Architecture and development of distributed applications
- Microservices, APIs and service-oriented backends
- Development of Kubernetes controllers and operators
- Resource scheduling, frameworks and cluster operations
- Debugging across service and system boundaries
What I offer
Technology with the bigger picture in mind
I support companies where software engineering, operations and established IT systems meet. The scope depends on the actual need – from focused consulting to implementing a complete technical initiative.
01
Software Engineering
Individual applications, APIs and services – planned pragmatically, implemented cleanly and maintainable over the long term.
- Analysis and technical design
- Backends, interfaces and automation
- Maintenance and further development
DevOps & Automation
Reproducible processes, containers, CI/CD and infrastructure as code for less manual work and more transparency.
- Build and deployment processes
- Docker and Linux environments
- Documented operations
Clusters & Containers
Experience with Apache Mesos, ClusterD, Kubernetes, Docker, service discovery and distributed systems – from architecture to operation.
- Architecture and technical assessment
- Frameworks and services
- Debugging distributed systems
Legacy Modernization
Understanding, securing and gradually modernizing OS/2, mainframe and established software environments.
- Assessment without a big bang
- Step-by-step migration
- Preserving valuable domain knowledge
Technical focus
Experience that helps in practice
Distributed systems
This is my central focus: service-oriented architectures, microservices, APIs, resource scheduling and the interfaces between them. I keep behaviour, operational safety and failure scenarios in the overall system in view.
Open technologies
Linux, Docker, Apache Mesos, ClusterD, Kubernetes, Go, Python, JavaScript, CI/CD and automation are among my technical areas. I choose the concrete tools for the project rather than following a rigid product catalogue.
Products and projects
Public projects and contributions include ClusterD, Mesos Compose, M3S, Traefik, Apache Airflow, TensorFlow on Mesos, the Mesos Firecracker executor and Docker volume services. Further projects include Weave, M3S and Mesos Compose. View ClusterD as a product ↗
How collaboration works
Traceable from the first conversation to operations
Propose
You receive an understandable technical assessment with sensible next steps – without unnecessary complexity.
Implement
I work in verifiable stages, record decisions and make risks visible early.
Hand over
The result is traceable code, documentation and a realistic view of continued operation.
Frequently asked questions
What potential customers want to know
Which companies are the services suitable for?
I support companies and technical teams that develop individual software, operate existing systems or want to modernize established infrastructure step by step.
Do you also take over existing projects?
Yes. Collaboration can begin with a technical assessment, troubleshooting or documentation. Existing code and systems are understood first before changes are proposed.
Can consulting and implementation be combined?
Yes. I can prepare a technical assessment, design a solution and then support implementation in verifiable stages.
Which information is useful for an initial enquiry?
A brief description of the current situation, the desired goal, existing technologies, relevant dates and known constraints are helpful. Complete technical documentation is not required for initial contact.
Direct and personal
One contact. Clear decisions.
I work as a solo business with technical depth and short communication paths. Knowledge therefore stays in the project, questions go directly to the right person and decisions can be made without unnecessary coordination.
Every project begins with an understandable assessment of the current situation. Solutions then fit the existing requirements, teams and resources.
I do not promise a generic standard solution. I show transparently what makes sense, where the limits are and which steps provide the greatest benefit first.
Next step
Do you have a technical initiative?
Write to me briefly about it. Information about the current situation, goal, timeline and existing infrastructure is helpful. I will reply personally.
For new customers, an initial consultation is free of charge. It is suitable for consulting, technical design, development, migration, automation, remote support for Linux and OS/2, and operational support.
