About

Passionate about artificial intelligence, software development, and the ever-evolving world of emerging technologies, I have over three years of experience in the Data, Machine Learning, and MLOps industry. My curiosity drives me to continuously learn and explore the latest advancements in AI, cloud computing, and automation. Currently, I am deepening my expertise in MLOps, researching and implementing best practices to streamline the deployment and scaling of machine learning models. I have hands-on experience working with AWS and GCP, leveraging cloud technologies to build scalable and efficient AI-driven solutions.

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
