> Software engineering for open academic data. I am a software and data engineer and a Computer Science student at IME-USP. I love to study, and I am autistic: I think best in structure, formal notation and small, careful steps. I spend my time where information retrieval, data engineering and behavioral science meet, and what I build most today is USP Aberta, a platform that makes the research of the University of São Paulo searchable.

## Work
- [USP Aberta](https://xnths.com/en/work/usp-aberta): An open-data platform that makes the research output of the University of São Paulo searchable: faculty, units, publications, collaboration networks, innovation and events, built from Lattes curricula and open sources.
