It seems like everyone in tech does this. Someone has a mind blowing feat of engineering, but leave out the part where they cheated and arguably lied about it because "it's just some minor detail that doesn't really matter"... For some reason they think these are bragging points that put them above all other engineers.

"I built a calculator completely from scratch by myself with no help" (by importing calculator.*)

"I invented my own cloud microservice in a language I wrote completely myself" (It's hello world split in 2 files on google drive and the language is just JavaScript but it you added a "framework" (it's single method) that already exists in the wild but your version is slower and worse)

"I built my own computer" (by buying a prebuilt computer but swapping out the ram, or buying an essentially prebuilt computer but it comes disassembled)
