We build software that works

CroCoder is a software development company founded in 2018 and based in Zagreb, Croatia. Led by Andrej Mrkonjiฤ‡ โ€” a developer with over a decade of hands-on experience โ€” we partner with clients ranging from indie game studios to city governments to deliver tailored, high-quality digital products.

Whether it's porting a game to a new platform, architecting a scalable multiplayer backend, or building an accessible civic app, we take ownership of the full journey from concept to completion.
