Development

I develop software for businesses and non-profit organisations, drawing on experience as professional and volunteer contributor to various free and open source software projects.

OpenBSD

The OpenBSD project develops a UNIX-like general purpose operating system which is free, functional, and secure.

My areas of contribution include device drivers, IPv6, UTF-8 support, and wireless networking. I port existing software to OpenBSD and write OpenBSD-specific software.

Apache Software Foundation

The Apache Software Foundation (ASF) spans over 130 projects covering a wide range of frameworks and applications enjoying wide use within the industry.

As an ASF member I do my part in shaping the future of the ASF. I have been contributing to the widely-used Apache Subversion version control system for over a decade. I have also made contributions to APR, Apache HTTPD, and Apache Serf.

Others

Contributions to Osmocom, git, XFCE, Gnome, e17, Pulseaudio, Python, FreeBSD, freedesktop.org, OTR, ...

I will consider any project proposals involving free and open source software.

Consulting

I provide advice and training in open source development:

• Forge a lasting relationship with communities building the software you rely on
• Devise the best strategy to open-source an existing product
• Build a new open source community around your project
• Receive code review and mentoring for developers freshly exposed to open source

OpenBSD end-user support for setup, configuration, deployment, and maintenance is available on request. I provide hands-on training workshops about OpenBSD pf firewalls. My standard table of contents of detailed training exercises contained in a full-day pf workshop can be viewed here. I will customise and expand my written training material to meet your requirements and will make all of it available to you under a CC-BY Creative Commons License.

Ich biete OpenBSD Schulung und Support auch auf Deutsch an.

Together with elego I offer support and consulting services for the Subversion version control system.
