Testimonials
As a student at Cincinnatus, Oniel made a lasting impression due to his technical abilities, his enthusiasm for learning and being better, and his earnest desire to help other members of our community be better as well. When he wasn't making strides towards completing the program (to which he was also very committed), he would routinely be found helping others along. Even after graduating, we have continued to rely on him for support, and I have always appreciated his eagerness to continue mentoring those students who have come after him.
Oniel has extensive experience in both web and AR/VR technologies that make him a very competent developer. In general, he is a great software engineer with a great deal of knowledge in front-end and back-end development. He is constantly learning and does not stop when faced with a problem, he is conscious and persevering. It's always fun and very productive to work with.
