About Jonathan

Versatile consultant with 9 years of experience in IT consulting firms and service companies, I have primarily worked for large enterprise and institutional clients in the fields of development and cybersecurity.

I am particularly interested in projects with high added value and significant technical innovation potential: data analysis and exploitation, autonomous systems, emerging technologies.

My service offering is divided into three components: cyber risk analysis, custom solution development, and systems administration (Linux).
