The word "works" in the Bible

Here, what does the word "works" mean? Does it mean something like a product or result of your work or something that you made like a painting? The questions concern Ephesians 2:8-9 in the Bible, New International Version.

Ephesians 2:8-9 (New International Version)

⁸For it is by grace you have been saved, through faith—and this not from yourselves, it is the gift of God— ⁹not by works, so that no one can boast.
