Final answer:
The character from 'James and the Giant Peach' who works for a shoe manufacturer at the end of the story is the Centipede, who becomes a famous shoemaker.
Step-by-step explanation:
At the end of James and the Giant Peach, the character that eventually goes to work for a shoe manufacturer is the Centipede.
After the adventure concludes, the Centipede is recognized for his fine taste and becomes a famous shoemaker.
He devoted his time to designing and making exquisite shoes, which likely stemmed from the historical context where a shoemaker measured their feet in order to cut and stitch together an individualized product for each customer.
This occupation suits him especially well considering the number of shoes he would require himself, being a centipede.
