Recommend some Manhwas

Any manhwa where or do you have some lists where the MC (male of female) transported or reincarnated to another world or novel or otome game.

Specifically, I'm looking for an MC who's really good at something before he/she transported and use those skills to that latter place. Like MC is chef, doctor, engineer, etc. That would benefit to the plot.

Thanks in Advance (⌒▽⌒)
