Find which theme was customised or similar theme

Hello Everybody,
I am looking for a similar theme or the theme this site has used.

Any pointers would be helpful. Thank you in advance.

It’s custom built

It’s tough to find ones like this because it’s not really stock theme friendly. some authors tend to design in this style like https://qodeinteractive.com/ or colabrio's profile on ThemeForest or greatives's profile on ThemeForest

Thank you so much,
I settled for the Fastland theme and decided to work on it.
