Hi! I'm Guille, a Behavioural Data Scientist based in Spain with a background in electrical engineering and an MSc in Behavioral Data Science. I've worked as a Business Analyst at Santander Bank and recently designed a demographic analytics dashboard for UN ESCWA focused on Lebanon, handling everything from data processing to building interactive visualisations with Leaflet.js. My technical skills include Python, R, SQL, machine learning (Random Forest, XGBoost, clustering), data visualisation (Tableau, Shiny, Leaflet), and I'm comfortable with the full pipeline from wrangling to deployment (FastAPI, Docker, PostgreSQL). I'm drawn to projects at the intersection of behavioural data and social impact — particularly around wellbeing, mental health, education, or public policy — but I'm happy to contribute wherever the need is. I enjoy scoping messy problems as much as building the solution, and I work well in small, collaborative teams. I'm looking to contribute meaningfully to projects that matter while learning from others in the data-for-good space. Open to both short-term and longer engagements.
