Can I use a blockchain to save reputation of jobs

We are working in a project similar to
where the final user can ask for specialized services like plumbers or electricians
in exchange for payment. We are also thinking of bringing training and certifications
so we think of using for this purpose however we were thinking if the reputation of
the people can be also registered in a sort of blockchain.

Interesting use case. “Reputation” is typically done through reviews socially, like on AirBnb. However, it sounds like you are you proposing TaskRabbit issued certifications, that could be scanned and verified on site, to provide a higher level of confidence. Is that right? If so, I think that is a great use case!
