About
Julien Simon bridges the gap between AI research and enterprise reality. While many experts choose either academic research or practical implementation, Julien deliberately combines both. He reads research papers, decrypts the mathematical foundations behind breakthrough methods, and obsesses over translating them into shareable knowledge and solutions that actually work at scale.
With over 30 years of technology experience at AWS, Hugging Face, Criteo, and other major companies, Julien has built and scaled software engineering teams, architected enterprise solutions, and helped Fortune 500 organizations deliver measurable business value. His approach combines deep technical understanding with executive leadership, empowering enterprises to achieve superior AI outcomes while maintaining security and cost efficiency.
Julien's career reflects continuous learning across computing's evolution, always grounded in first principles. He's adapted from MySQL web platforms to Generative AI, from programming Motorola 68k processors to optimizing modern AI accelerators, from real-time operating systems to cloud-native architectures. Through every technology shift, he maintains a rigorous approach to building from sound fundamentals. Each new domain becomes an opportunity to learn, adapt, write code, and apply fresh concepts while staying grounded in fundamental engineering practices.
Julien's mission? To demystify buzzwords and cut through industry hype to focus on what actually works in production.
