I am the main founder and president of the Open Knowledge Association (OKA), a non-profit granting stipends to full-time Wikipedia translators. The articles we created are listed here. The work I do on Wikipedia and for OKA is during my free-time only, without any link to my full-time activity or to my employer.
My philosophy for life is Effective altruism. I fix what I find when browsing Wikipedia and try to contribute on pages where I feel that it would maximize my Social return on investment. In particular, I tend to focus on the fields of statistics, game theory, computer science and economics. I spend most of my time on the lead section of articles, on simplifying definitions and clarifying the differences between similar terms and topics.
