Hi, I'm Javier

I'm a Machine Learning Engineer at Avature and a PhD in AI / Data Science & Engineering from the University of Seville.

My work sits at the intersection of applied machine learning, time series, generative models and production-oriented AI systems. I have worked on forecasting, imputation, medical AI, renewable energy, industrial anomaly detection and autonomous agent evaluation.

Right now, I am especially interested in:

  • Reliable LLM agents, evaluation frameworks and personal AI systems.
  • Time-series forecasting, missing-data imputation and spatio-temporal modelling.
  • Generative modelling, diffusion/consistency models and practical ML research.
  • Applied AI for energy, health and biotech products.

Current Focus

  • ML Engineering: building and deploying machine-learning systems in real products.
  • Agent evaluation: creating reproducible ways to benchmark LLMs and autonomous agents.
  • Research-to-product: turning research ideas into useful tools, not just notebooks.
  • VenpraLab: applying biotechnology and data-driven thinking to biomethane and anaerobic digestion.
