Testimonials
“I have had the privilege of having Mario working at World Mobile, on our mobile applications team, and it is a pleasure to recommend him. On a technical level, Mario has proven to be exceptionally capable, especially in Kotlin Multiplatform development for Android. As a senior developer, he not only met his tasks but also took the initiative in multiple projects, providing innovative solutions and enhancing our team’s efficiency.
Beyond his technical skills, Mario is a friendly and collaborative individual. Always willing to assist his colleagues, his empathy and manners make working with him an enriching experience. His positive attitude and ability to work as a team make him an invaluable asset to any organization.
I highly recommend Mario to any company in search of a highly skilled mobile application developer who is also an excellent team player.”

“It was a pleasure working with Mario, and I hope to work with him again someday. I worked with Mario for approximately 3 years, during which I could see that he is a great person and a true professional. He is constantly growing and maintains a very positive attitude at all times, whether facing new challenges or assisting colleagues. Over these years, Mario became a technical leader in a complex technology like Leanback, which had limited information available. This demonstrated his ability to take on any professional challenge and also help us, his fellow colleagues, understand it.
Working with Mario was a pleasure, and he greatly contributed to the growth of his colleagues, doing an outstanding job“
