Chapucero
A hack or botcher. A worker, contractor, or technician who does a noticeably shoddy job, cuts corners, and always has an excuse for why the work failed or turned out wrong. (In the Dominican Republic, they often blame the country's unstable power grid for their own failed repairs).
That chapucero I called left my fridge exactly the same, and now he says the problem is that the power is bad here.
