About Toon

Aparte de mi experiencia con Python y Haskell también tengo conocimientos de POSIX sh, Java, SQL, HTML/CSS/JS, Scheme y Prolog.

Estoy familiarizado desde hace muchos años con sistemas Linux, ultimamente con un enfoque en especificación declarativa de infraestructura (o devops) con NixOS.

Contribuir a proyectos Open Source me ha enseñado trabajar con sistemas de integración continua (CI) y VCS como Git, así como con procesos de revisión de codigo y de triaje y respuesta a incidentes.

Mis estudios se han enfocado en técnicas de Machine Learning, sistemas formales para la verificación de software (Rocq, Agda, SMT solvers) y Programming Language Theory. Además, esto ultimo me permite aprender nuevas idiomas de programación con facilidad.
