Hi,

1+ year of experience developing software solutions across their entire lifecycle. Systems Engineering student and freelance developer based in Medellín, Colombia. I have collaborated with teams and clients to turn ideas into functional, scalable, and results-oriented digital products.

I can provide value in developing applications and systems, from initial conception to implementation and deployment.

about me

Software Developer (Full-Stack)

I am Brahian Ospina, 26 years old, and I am currently studying Systems Engineering at Tecnológico de Antioquia in Medellín, Colombia. My innate curiosity has always led me to seek how technology can positively impact people.

I divide my time between my professional career and my independent work, where I build Full-Stack applications experimenting with local AIs to return data sovereignty to the user.

My greatest motivation is my active research on racial biases in LLMs applied to psychiatry. I firmly believe in building technology that is not only efficient, but also transparent, fair, and ethical.
