Hi, this is Masum-al-hasan Rocky (Bengali: মাসুম-আল-হাসান রকি). I am from Bangladesh. I have been a Wikipedian since 2013. I mainly work on Wikipedia, Wikimedia Commons, Wikidata and Wikivoyage. I have attended and organized several off-line Bengali Wikipedia promoting events since 2015. I am the founder of the first ever Wiki Club in Bangladesh. I was involved as a co-founder of Rajshahi Wikipedia Community, which is a divisional user community of local Wikipedians from Rajshahi Division under the local chapter Wikimedia Bangladesh. I am serving as a Member in the Executive Committee of Wikimedia Bangladesh since 2016 and currently serving as a Treasurer. I am one of the administrators of Bengali Wikipedia.
