Stefan Sperling - FOSS Developer and Consultant
Freelancer based in Berlin specializing in Free and Open Source Software
- FOSS: Free and Open Source Software
- Software which can be used, shared, and modified freely.
Development
I develop software for businesses and non-profit organisations, drawing on experience as professional and volunteer contributor to 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 help with porting existing software to OpenBSD and developing OpenBSD-specific software.
Apache Software Foundation
The Apache Software Foundation (ASF) is a US 501(c)(3) non-profit corporation supporting open source communities using a collaborative development model. Over 130 ASF projects cover a wide range of frameworks and applications which enjoy wide use within the industry.
As an active ASF member I work with and for ASF projects and do my part in shaping the future of the ASF.
I have been contributing to the Apache Subversion project for almost a decade.
Others
Contributions to xfce, gnome, e17, pulseaudio, python, freebsd, freedesktop.org, OTR ...
I will consider work proposals involving any project in the free software community.
Consulting
I provide advice and training in FOSS development methods for businesses getting involved with open source communities. Problems I can help solve include:
- Improving your relationship with communities building the software you rely on
- Devising the best strategy to open-source an existing product
- Building a community around a new project idea
In cooperation with Berlin-based company elego
I offer support and consulting services for the
Apache Subversion version control
system.
OpenBSD end-user services such as support for system setup, configuration, deployment, and advice on picking hardware and software for products based on OpenBSD are available on request.
