Juan Arturo Sánchez

Data and research analyst specialised in public opinion, survey-based research, and policy evaluation.

With over four years of experience in public policy and development contexts, I support NGOs, consultancies, and research teams in designing and analysing surveys, conducting structured desk research, and producing clear, decision-ready reports.

My work combines quantitative and qualitative methods, including statistical analysis in R and Python, survey design and deployment using Qualtrics and KoboToolbox, documentary review, interviews, and case studies.

I have contributed to evaluation and research projects for public administrations, university research centres, and international civil society organisations. This includes large-scale surveys with 1,500 to 7,000 respondents, cross-country evidence synthesis, and the production of analytical outputs under tight timelines.

As an independent consultant, I led the methodological design and coordination of a national electoral observation mission, overseeing survey deployment, stakeholder coordination, and final reporting.
