From Stardew Valley Wiki

ConcernedApe (Eric Barone) is the creator and lead developer of Stardew Valley. He programmed the entire game (except multiplayer networking in 1.3) and created all art, sound effects, and music. He currently resides in Seattle, Washington. See Stardew Valley for more info about the game development.

In early 2019, ConcernedApe hired a small development team to continue updating the game. Version 1.4 of the game was developed by ConcernedApe, Arthur Lee (a.k.a. Mr. Podunkian), and Alex Erlandson (a.k.a. zillix).
