I created some languages in my teenage years - on paper, before the internet age; I'm now going to put them online.
But also start some new ones, based on new ideas.
I've learnt about languages and linguistics since childhood, and studied linguistics at university. Recently I have been answering a lot of language questions on Quora.
My current main conlanging focuses are engelanging (especially experimental langs), grammar especially syntax, taxonomic languages, ideographic writing systems, word formation.
I'm also interested in trying to catalogue all known conlangs, and in classifying and categorising them.
