I read, write, and sometimes speak in English.
I've written and co-authored a number of public reports and research articles, mostly within the domains of urban geography and planning. Several of these are listed on my occasionally updated Google Scholar and ResearchGate profiles. I've also written a number of shorter pieces (e.g. online articles, tutorials, etc.) that I'll hopefully list and link to from here in the future.
For a few years now, I've also been tracking what books I read. A little while ago I made this reading ladder-timeline-chart-thing to try to visualize my reading trends. Maybe I'll update this or make something similar sometime soon (:
