Hello, This is Tanweer. I am a Bangladeshi Wikimedian, contributing in Bengali Wikimedia projects and also here in Commons. I've been voluntarily working for Wikimedia Bangladesh as a founding board member since 2011. Please use my Bangla Wikipedia Talk page to talk to me, as I'm mostly available there. Or you may email me at wiki.tanweergmail.com for fastest response.
Before using my photos outside any Wikimedia projects, I would like to request you for two things:
Please let me know that you intend to use my photo/photos.
If you publish any derivative works from my photo/photos, than you should publish that/those under the Creative Common Attribution Share Alike 4.0 license.
Thanks for your understanding. You can view most of my uploaded photographs here. Here are some of my photos that I uploaded in Commons.
