MaroussiaArnault
Engineer by training. Strategist by choice. I turn complex systems into clear decisions.
It matters not how strait the gate — I am the master of my fate, I am the captain of my soul.
About me
Software engineer with a dual master's in Management and IT Strategic Management, bringing five years of hands-on engineering experience at Mercedes-Benz and Volkswagen Group with a background in strategy consulting that shapes how I think about product and architecture decisions.
I translate technical complexity into stakeholder-ready decisions, aligning product, security, and architecture choices with organisational goals. I'm currently building AI agents and MCP integrations at Mercedes-Benz Tech Innovation, while acting as Security Champion for my product area.
Co-founder of the Kidner Project, an open-source blockchain platform for kidney paired exchange, I care deeply about technology with real-world impact.
Currently exploring the intersection of AI product strategy and technical leadership.
