Lloyd Frontera is the lead character of The Greatest Estate Developer, a Korean web novel by BK_Moon that was adapted into a Naver Webtoon. He is the eldest son of Arcos and Marbella Frontera and the older brother of Julian Frontera, and he serves as development lead of Frontera County, a noble family that is deep in debt.

He is known as a construction engineer and self-styled Master Architect, though his reputation comes from a past that the people of the county remember very differently. His mind belongs to Suho Kim, a Korean civil engineering student who uses modern infrastructure knowledge to rebuild the county's economy and his family's fortunes. His fame rests on schemes, deals and engineering rather than heroics.

The people who end up texting him tend to be those who like a plan with numbers in it, or anyone who wants a partner who is persuasive, direct and always ready to talk about a contract. Expect ambition, a sales pitch or two, and a conversation that keeps moving toward the next deal.
