Sebastian Montero

AI Engineer building intelligent systems at scale.

Based in London, originally from Costa Rica. I build AI and machine learning systems, with experience spanning data science, deep learning, recommendation systems, and LLM & agentic systems.

Right now, I’m focused on multi-agent systems. From experimentation and discovery to production deployment, monitoring, and optimization. I’m passionate about pushing what’s possible with AI while keeping a strong focus on real-world impact.

Outside of engineering, I’m into music production, analog photography, films, and Brazilian Jiu-Jitsu. Always exploring, always learning.
