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

Angie Katherine Reyes

AI Builder & Team Lead @ Nequi

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.
