03 // EDUCATION & BIO
About Me & Education
Passionate about computer science, algorithm efficiency, and in-depth engineering.
I'm Genaro Febbo Yapur, known in the developer community as GefyDev. I'm fascinated by how systems work under the hood: from memory safety and native efficiency in Rust to building lightning-fast server-rendered web platforms with Astro, TypeScript, and React.
I am currently pursuing a Bachelor's Degree in Computer Science at the prestigious Faculty of Exact and Natural Sciences of the University of Buenos Aires, following my graduation from the historic Colegio Nacional de Buenos Aires (CNBA). This provides me with a deep mathematical foundation and rigorous analytical problem-solving skills.
I enjoy architecting tools that empower communities and open-source ecosystems, optimizing every single byte while crafting enjoyable visual experiences.
