Hi, I'm Louis. I build AI-powered SaaS platforms using Next.js, Python & LLMs.
About me
I'm an engineer with a Computer Science degree specialized in Big Data & AI from EFREI. What drives me is the intersection of full-stack development and artificial intelligence, where I can build innovative solutions that solve real-world problems. I work primarily with Next.js, React, Python, AWS, and LLM SDKs, crafting scalable applications that leverage the power of modern AI. I'm currently open to new opportunities as an AI Engineer, Data Scientist, or Full Stack Developer.
