Pretty sure senior developer applies by now even though I never wanted that title.

Did C, .NET, Java, JavaScript, a ton of python and a load of ecosystem libraries most of which I cannot even remember anymore.

I still dislike C++, because it's still just too big and even if you can do almost everything, the workarounds to get it done are just too annoying.

Beyond languages, my current primary work areas include Spatial Data, Semantic Web, Knowledge Modelling, Description Logics, and "Service Management"

Ah, and if you care, I'm the author of the LillyTab SHOIF(D) reasoner: https://github.com/pwub/lillytab.
