When I worked as a lawyer, one of my tasks as a junior was to check the court lists every day against the spreadsheet of clients we had who were involved in litigation. If their name appeared then I had to send an email to the relevant lawyer containing the information.
This took about 30 - 60 mins each day and was monotonous. Just copying and pasting the client name into the browser search tool.
I automated the process, making a small website which lawyers could add their client and would receive an email if the name appeared in the court lists. I ended up turning it into a small SaaS business for a while and sold a licence to my company.
Not a huge victory but it felt great at the time!
