CARMENES is a high-resolution optical and near-infrared spectrograph(s) mounted at the 3.6m telescope in Calar Alto, Spain. The CARMENES exoplanet survey began in 2016, targeting over 350 nearby M-dwarf stars. Since then, CARMENES has proven to be one of the most effective Radial Velocity (RV) exoplanet finders currently in operation. I will briefly present the CARMENES-GTO Doppler survey, its scientific goals, and I will focus on some of the exciting CARMENES-GTO exoplanet discoveries. I will show that CARMENES is fully capable of discovering complex multiple-planet systems around late M-dwarf stars, which cannot be studied by other instruments. I will reveal the powerful synergy between CARMENES and the Transiting Exoplanet Survey Satellite (TESS), leading to a dozen exoplanet discoveries. One of the most exciting CARMENES discoveries, confirmed by TESS, is a nearby transiting rocky exoplanet that will be a prime target for atmospheric investigation and characterization with the JWST. The precise orbital determination based on CARMENES precision RVs is vital for probing the planetary formation mechanisms and evolution scenarios around low-mass stars and in general.
