About
Hi, I'm Nafis Sadik Zim
Lecturer, Shahjalal University of Science and Technology (SUST)
I built this toolkit for my students. Many small tasks — converting papers into notes, pulling figures out of reports, cleaning up documents — eat up time that is better spent learning. These tools take care of the boring parts so you can focus on what matters.
Have an idea for a tool that would help you? Tell me in class — the best suggestions get built next.
