Ask HN: What's a niche problem you'd pay someone to solve?

I'm a computer science student thinking about building and maintaining a small service or tool alongside my studies. Ideally, it would generate a bit of extra income to help cover tuition.

I haven't found an idea yet, so maybe one of you has a specific idea or knows a way to get one.

I do not try to find a million-dollar startup idea (more than enough people are doing that), just small, genuine pain points that might translate into a simple, paid solution.

Thanks in advance!
