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.
Others
Contributions to 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. Your firewalls have never been happier than this!
Together with elego I offer support
and consulting services for the Subversion
version control system.
