Hi, I am Mahmud Ridwan. Email:

I started my career in the industry as a remote freelance software developer in 2010. I completed my B. Sc. in Computer Science at the end of 2012. During my years in academia, I fell in love with competitive programming.

I started Furqan Software in 2015 and turned my pet project into Toph. Today, Toph is the leading competitive programming platform in Bangladesh.

I like free software, and I enjoy making them.
