" I had the pleasure of working with Željko at Open Cosmos, where he worked as a Golang Engineer. Throughout our time together, Željko consistently demonstrated great technical expertise and problem-solving abilities. Beyond his technical skills, I truly appreciated Željko’s strong soft skills. He is an excellent communicator, a great team player, and always approaches challenges with a collaborative and positive mindset. His ability to foster productive discussions made working with him both enjoyable and highly effective. I highly recommend Željko for any Golang engineering role. His combination of technical expertise, strong interpersonal skills, and dedication will undoubtedly be an asset to any organization."
