Other gifts and abilities I can offer:
I am here to help. You can utilize my broad knowledge from more than three decades of experience in Information Technology. I have likely already seen a situation like yours and know the hidden challenges and opportunities. I have been involved with numerous large scale IT projects, including international ones, for various Christian organizations, acquainting me with their special needs. I am keenly aware of security issues and understand the need to develop and maintain these projects on a tight budget.
My current part time employment provides me the opportunity to assist small businesses or households with IT improvements without it costing you the normal high cost of IT support. I can offer solutions at a minimal cost, solutions that require little effort and are thus efficient for you.
If you are looking for a German in Germany for managing events, having an address in Germany or similar tasks, I can recommend my wife’s Büroservice Marion Stut (German language only).

When starting to use Mitmproxy (see also my blog post about setting it up), you need to remember a significant number of details. To help you in this, I have compiled frequently used items in “cheat sheet” style - no background explanation, but a concise list of vocabulary. Much of this is copied, selected and rearranged from http://docs.mitmproxy.org/ . In the first sections, I’m only listing what I regularly need, while the Appendices contain the full data.
In this post, I’m describing what it takes to set up a website and a few email addresses, if your usual web hosting company won’t do it at a reasonable price. None of these steps are unusual, but it is nice to have them written down in one place, including working examples of the syntax. The target audience are IT technicians, who might end up doing this for several domains.
I have heard of too many stories of browser add-ons reporting innocent user’s browsing history to data vendors, disguised as “anonymous usage statistics”, which later turns out to be not very anonymous, but easily traceable to individuals. I have set up an environment to check what really happens. This includes intercepting SSL traffic, which in theory should be hard, but in practice is easy, by using Mitmproxy as a web proxy.
If you are responsible for the Intranet of any kind of organization, you probably want to make sure that only authorized users know what’s written in there. But usually, unless you take measures described below, external sites are able to map out your Intranet. Most likely you do not want this mapping, because you are operating it as an Intranet for a reason. This is how the mapping can work: It starts with Intranet pages containing links to external sites, e.g. news sources. Each time an Intranet user clicks on such an external link, the user’s browser will send a referrer field to the external web server as part of the HTTP request headers. This referrer field contains the URL of the (Intranet) page the link is placed in. This enables the external site to map your Intranet.
NextCloud is a server application, primarily providing a file synchronisation service, very similar to Dropbox. Calendars, tasks, contacts and a number of other services are available as add-ons. It can, and is meant to, be hosted on your servers, possibly on-premise, thus eliminating the privacy issues associated with external cloud providers. NextCloud is open source. You can install and use NextCloud free of charge for any purpose, personal and commercial. The server software is complemented by client software for the file synchronization service, free for Linux (todo try Linux client), Mac, Windows Android, small fee for iOS. For calendar, tasks and contacts there are many clients, most notably Outlook CalDAV Synchronizer on Windows and Lightning for Thunderbird (calendars and limited tasks, Linux, Mac, Windows). iOS can connect natively, Android needs a paid app (CalDAV Sync and CardDAV Sync by Marten Gajda, 2.89 € and 1.79 € respectively).
