About me

I'm a Software Engineer and Summa Cum Laude graduate of Universidad APEC, passionate about building products where technology and design meet.

Through the Harvard CS50 courses (CS50X, CS50P, and CS50W), I built practical skills in Python, Django, SQL, Flask, JavaScript, and React, strengthening my foundation in both back-end and front-end development.

With a focus on clean and intuitive design, I bring a unique approach to software development: it is not only about writing code, but about crafting visually engaging and easy-to-use interfaces that improve user experience. Combining technical skills with a designer mindset helps me build interfaces that look great and perform consistently.
