How I got here
Early on
Taking things apart
I was the kid who wanted to know how everything on a computer worked, and how a screen full of pixels became something you could actually use. That curiosity stuck.
University
First real project
During my specialization internship I wrote my first real web project. Seeing an idea go live in the browser, where anyone could open it, is what got me into web development.
2021
Founding MHLSQ
I founded MHLSQ to build products for real people, then went from internships to a full-stack role at Huawei. Along the way I learned to write code I can still defend six months later.
Today
How I work today
Every project starts with questions: who it is for and what ships first. I build from reusable components and treat speed and accessibility as requirements from the first commit. A launch still gives me the same rush it did at the start.
