Alvarado.

I build advanced analytics and AI solutions designed to solve real problems, turning raw data into tools ready to make a business impact.

About.

I'm Raúl Alvarado, a data analyst and scientist. I have over 5 years of professional experience working across the full data lifecycle: from raw data extraction, preparation and cleaning, to building predictive models and dashboards for strategic business decision-making.

Throughout my career at companies like Banco Sabadell and KPMG, I've seen first-hand the real value of data and how good data management transforms decision-making in an organization. From that business perspective, my priority is that the solutions I build —from a data pipeline to an advanced model— are interpretable, sustainable and genuinely useful.

To stay current and keep deepening my knowledge of the latest technologies, I'm currently finishing a Master's in Artificial Intelligence. I'm committed to continuous learning and professional growth, and I dedicate part of my time to researching new tools, complementing my knowledge in other key areas, and putting what I learn into practice.
