Hi. I’m Estefanía León.
AI Engineer.

I didn’t arrive at machine learning through a straight line. I started with a degree in video game design and interactive content — learning how structure, feedback, and interface decisions decide whether a system actually works for the person using it. That instinct for structure is what later pulled me toward representation learning: wanting to see the actual shape of things, not just their surface.

The bridge was research. While building web and VR projects, I was also analyzing CERN ALICE open data and training deep learning models to classify particle interactions — my first real exposure to a field that holds models to a standard most industry work never has to meet. Two master’s degrees later (IoT & AI, then Big Data), that research habit turned into a full engineering discipline.

Today I’m an LLMOps Engineer at Natura & Co, designing production conversational AI systems and the architecture that keeps them fast and affordable at scale. In parallel, I’m a research student with CERN openlab’s Next Generation Triggers initiative — a focused, two-month residency, not the whole story — and I’m pursuing a PhD in Quantum AI and Optimization. Outside of all that: Hyrox training, and finding reasons to travel.
