About Jonathan

I transform clinical and platform data into clear, actionable decisions.

As the founder of MindKos, I help mental health centers, research teams, and digital platforms make evidence-based decisions. I combine psychometrics, statistical analysis, and data visualization to improve retention, validate clinical outcomes, and optimize processes.

I work with tools like SPSS, R, Jamovi, and Power BI, integrating lightweight predictive models and cohort analysis. My reports are reproducible, clear, and designed for clinical, product, or research teams.

I collaborate with organizations across Europe (in Spanish and English), on both short diagnostic projects and broader strategic consulting.
