About Guillermo

Hola, soy Guillermo, ingeniero en IA y ciencia de datos con experiencia en proyectos de neurotecnología, salud y automatización. Trabajo tanto con empresas españolas como internacionales, ayudándolas a integrar soluciones de inteligencia artificial y modelos generativos.
I hold a Master’s degree in Computational Cognitive Science from the University of Groningen and a Bachelor’s in Biomedical Engineering from the Polytechnical University of Valencia. My experience bridges AI, neuroscience, and software engineering, combining strong coding skills with real-world research and startup experience.
I’ve worked on diverse projects — from neurotechnology and biosignal analysis (EEG, EMG, ECG) to protein design with generative models, AI-driven automation, and AI-powered app development (Flutter, Python, MATLAB, R).
Currently, I help companies integrate cutting-edge AI solutions — from data pipelines and custom model development to implementing LLMs, image/signal analysis, and automation workflows.
I’m particularly passionate about AI for health, biotech, and human–machine interaction, but also open to general AI development and automation projects.
Let’s collaborate to bring AI ideas to life — fast, efficiently, and ethically.
