About Me
Hello, I'm Léonel! I am a Mathematical Engineer and Data Scientist driven by the mission of bridging the gap between rigorous mathematical research and practical AI deployment.
With a background in stochastic modeling and statistics, I specialize in transforming complex theoretical ideas into robust AI prototypes. I am particularly passionate about Machine Learning, Large Language Models (LLMs), and Computer Vision, where I focus on improving both the performance and the theoretical foundations of modern models.
My goal is to take mathematical insights and turn them into experimental solutions that solve real-world problems. I thrive at the intersection of abstract analysis and high-performance engineering, always looking for new ways to make AI more robust and understandable.
