Back to original languageAbout Arnaud
Passionate about technological innovation, I have built a career combining technical expertise with a global vision of information systems, thanks to a dual background as a computer engineering graduate from ENSICAEN and a management graduate from ESSEC.
Throughout my experiences, I have developed solid expertise in Cybersecurity, AI, Data, Cloud, and Application Development. I currently work as a CTO / AI Tech Lead / Cybersecurity Architect / Lead Developer, with an approach focused on security, architecture, innovation, and value creation, closely aligned with business objectives.
I have worked in various environments including startups, VSEs/SMEs, large corporations, and the public sector, which have allowed me to adapt to diverse contexts, maturity levels, and strategic challenges. I am also comfortable in an international environment and fluent in French, English, and German.
Curious and constantly learning, I aim to continue evolving on high-impact projects at the intersection of my areas of expertise in Cybersecurity, AI, Data, Cloud, and application development to support organizational transformation and technological innovation.
