Acerca de Chus
I help companies build AI systems that need to be accurate, fast, and reliable in production. My work focuses on high-impact NLP and LLM problems: improving extraction quality, hardening ML pipelines, evaluating real-world model behavior, and optimizing systems when latency, reliability, or weak evaluation are blocking business value.
I’m most useful when the problem is technically difficult or expensive to get wrong. That includes underperforming NLP systems, fragile AI workflows, unclear evaluation, or inference setups that are too slow or too costly. In one consulting engagement, I rebuilt a PII-masking pipeline, improving global F1 by around 20% while making it roughly 30x faster than the previous setup.
My background combines applied machine learning, research, and systems engineering, so I can work end to end: problem framing, data, experimentation, model and pipeline design, testing, CI, deployment, and optimization. I work well with teams that need strong technical ownership, fast ramp-up, and rigorous execution on complex AI projects.
