>The idea is that this tool should be useful not just for me but other freelancers, students, etc. who might be in my shoes.

In my opinion, you should start with this. Should, might, freelancers, students, etc...

Hypotheticals that are allowed to survive and vagueness of the target audience do a better job at filling up code cemeteries than does the stack choice.

Now... if you don't care about the outcome or building something useful and don't mind spending a lot of time on the thing for the sake of it and only want to do this project as an excuse to learn a technology, then by all means have at it. Then again, you'd have made up your mind about the technology you want to learn.

If you want to build something useful, starting with the technology is not the way to go.

All the best,
