Description

My name is Juan Peralta. I was born on July 19, 2004 in Valledupar, Colombia. From an early age, I have been fascinated by the world of programming and have cultivated an insatiable curiosity to learn as much as possible about it.

Currently, I am finishing my studies in Systems Engineering and I am also completing a technologist in Software Development. My approach to programming is not limited to just writing efficient code, but I also seek to build impactful and positive solutions, I am strongly committed to quality and excellence in all projects I am involved in.

I have been fortunate enough to gain experience in several programming languages, but my main focus is on JavaScript and TypeScript, using the Express framework. In addition, for data analysis, I rely on Python. I am always open to learn and improve, so any additional suggestions you can offer will be very welcome.
