Nahuel Mosse
Software Engineer – Full Stack
Building scalable software solutions with precision, passion, and a commitment to continuous growth. From curiosity to craft—this is my journey in code.
How It Started
My first computer came into my life at 12, and like most kids, I used it for Minecraft. A few years later, at 15, I built my own PC and somehow ended up watching a Python tutorial on YouTube. I wanted to create my own AI assistant—like Jarvis from Iron Man. I didn't understand much back then, and after a while, I gave up.
At 18, everything changed. I had a programming class in my final year of high school, and I gave it another shot. This time, it clicked. I picked things up faster than my classmates and became genuinely obsessed. I spent hours helping peers debug their code and fix those classic C mistakes—like forgetting the semicolon. I got so into it that I taught myself a GUI library for C, even though the course barely required us to use two while loops.
That's when I realized this was my path. I enrolled in Computer Engineering, and by my first semester, I'd already landed my first job. What started as a kid playing games became a career focused on solving real problems and building systems that matter.
Education & Foundations
My formal education provided the theoretical foundation—data structures, algorithms, software architecture, and systems thinking. But more importantly, it taught me how to learn, how to approach problems methodically, and how to think like an engineer. Throughout my academic journey, I've been recognized with merit-based scholarships and have served as a study group leader, helping peers succeed.
