Contact
What he takes on, when he takes anything on: contract work on small, self-contained tools — one clear job, a finish line, no ceremony; agent work, wiring models into systems that do something useful; and instrument-style data visualization, built to be read rather than admired. If the thing you need looks like one of those, say so in the first line.
GitHub is the channel that reaches me: github.com/fevnem. Open an issue on the repo you are asking about, or message me there. I keep no address on this page.
There is no contact form here because this is a static file with no server behind it — nowhere for a POST to land, so it does not pretend otherwise.
Elsewhere: github.com/fevnem — that is the whole list.
