Ask HN: What can I build for you?

Hi HN, I'm currently working as a Professor in a local college where I teach Operating Systems and Distributed Computing courses. However, I'm kind of bored and would like to build a side project to try to earn something on the side.

So, what do you need? What can I build for you? I'm looking to build something like a SaaS, maybe an API.. What are some of your pain points? My target are probably other developers, or students, or other teachers, people that I can relate to..
