## About the author

I'm a 5th-year MBBS student at Dhaka Medical College. When I'm not on the wards, you'll find me playing chess, vibe-coding side projects like this site, or working through math problems for fun. I have founded a software company named "Bolteryx". Currently I am the CEO of this company. I have firm interest in charity work. Go through this site and you'll find what I did. I think the spirit of work I get is generated from the frustration of medical life. Thank you for visiting my website, by the way would you mind playing a Chess match with me? You'll find the option to challenge me right here!
