Calerga offers also consulting and engineering in the domains of dynamical systems and control, understood with a broad meaning: system modeling, simulation, optimization, control, data processing, implementation in embedded systems. Here are some examples of projects it has realized:

Most of these projects require excellent programming expertise. Among the technologies Calerga has developed, one should mention numerical computing, programming languages (interpreters and transcompilers), reading and/or writing files in different formats (XML, JSON, MAT-file, LaTeX, PDF, Office Open XML (.docx and .xlsx), OpenDocument (.odt and .ods), VRML/X3D), and Internet-related protocols (HTTP server, WebDav, websocket, LTI). Main programming languages include C, C++, C#, Java, JavaScript and Python. Calerga also relies on third-party solutions when the project allows it. Thanks to its broad experience, it adjusts quickly to new environments.
