By "résumé" I mean "a document representing my background and skillsets."

This résumé is **incomplete**, as it only presents educational background at the moment. Download the pdf version of my résumé: cv.pdf.

I had my formal education from kindergarten, elementary school, junior high school, secondary high school, to universities, and I had formally worked for several institutions and companies in several countries.
