About

I spent ~4 years at Anthology/Blackboard on enterprise edtech: React and TypeScript frontends, Java and Spring Boot APIs, PostgreSQL and CI/CD pipelines for institutions at scale.

Before that, I worked on backend and cloud systems at Digital Americas Pipeline Initiative. I also take on selected freelance WordPress projects through Sal & Picciotto, contribute to the digital ecosystem at Facultad de Comunicaciones y Filología, Universidad de Antioquia and to Babel Scores, while pursuing neuroengineering research aligned with my master's program.

Research

Motor imagery decoding, FBCSP feature extraction, and subject-disjoint evaluation for non-invasive BCI systems.

EEG-based motor imagery classification at Universidad de Antioquia: bridging signal processing, classical ML, and software engineering.

My master's research tackles motor imagery classification from EEG: distinguishing imagined left-hand vs. right-hand movements from noisy scalp recordings. This is a foundational building block for non-invasive brain-computer interfaces that could assist motor rehabilitation or device control.
