Shoddy means badly made or badly done. Shoddy work, a shoddy repair, shoddy treatment.
It carries contempt rather than mere criticism, and it implies somebody cut corners knowingly. Shoddy was first a noun: cloth made from shredded old rags, which looked passable and wore out fast, and the adjective grew straight out of that.
