Sebastian Montero

Engineer. Building agents (with agents).

Based in London, originally from Costa Rica. I build software with experience spanning data science, ML, recommendation systems, LLM workflows, and agentic architectures.

I'm building tools for financial applications using multi-agent systems that reason, execute code, and coordinate autonomously.

Outside of engineering, I'm into cooking, analog photography, and films. I'm a blue belt in BJJ, but currently obsessed with climbing.
