Innovation is a challenging task today: we want to provide you with the best answers to your questions.
We often find out that we need both a deep understanding of the world where we all live in and make use of virtual spaces. A successful project needs a model of the physics involved, providing information to the processing system and state of the art computer systems.
We decided to provide you with all of this by using a powerful synergy: state-of-the-art software competences, prototyping capabilities, physical modeling.
Alter Ego Engineering is a company specialized in the field of civil engineering and mechanical engineering: its core business is numerical simulation.
We also have strong skills in software development, so we can help you with many kind of innovative technologies in this field. In addition to our engineering activities, we also offer project management services.
We also look at the future: our main effort is in combining all these knowledge with modern technologies in the artificial intelligence field, in particular in control system environments. This is not an easy task and we are working very hard to achieve it with the same rigor we use in more traditional fields.
