About

I have been in artificial intelligence for a good while — I started on the ML and data science side, and evolved until landing where excites me most today: GenAI and conversational agents. Now I lead a team where we build real things with language models, not just lab experiments. I move comfortably between theory and "okay, but how do we actually make this work?" I design agent architectures, work with LLMs, and think hard about how generative AI can solve concrete problems. If you are here it is because you are curious too — so we are on the same wavelength.

Fine-tuning at Nequi: Teaching a Small Model the Language of Our Transactions

FORMAT: WorkshopLEVEL: IntermediateLANGUAGE: Spanish

At Nequi, a transaction is not just an amount and a date — it is behavior, context, and sequence. Generalist models do not capture that semantics, and rigid rules do not scale with millions of users. In this workshop we explore hands-on how to fine-tune a small model so it learns the language of transactional events: their patterns, anomalies, and risk signals. Participants will work from dataset construction to model validation, understanding at each step which decisions matter and why
