I am an IT consultant based in Sheffield, England. I have previously specialised in systems- and network-administration, email systems (esp. qmail/netqmail, Postfix, Sendmail, Exim) and Linux/Unix; I've recently been adding Python and Ansible to that list, new skills I'm very keen to exploit.
I will be happy to discuss your current goals, to see how I can help you achieve them; please contact me. I normally work in English; Deutsch ist auch möglich.
For smaller troubleshooting type tasks I typically work remotely using SSH; for larger projects it may be better for me to be on-site. I've travelled extensively to fulfil client needs, so wherever you're based, I should be able to reach you.
