Good afternoon!

I'm Mario, a creative frontend engineer.

About

Here's a quick intro about me and what I love to do

My programming origins

When Apple unveiled the first iPad with its beautiful 1024x768 display, I knew I had to create for it. I taught myself mobile development while freelancing, and soon I was shipping iOS and Android apps. As the ecosystem evolved, I built on that foundation with React Native, creating cross-platform mobile experiences using the same component-driven thinking I loved on the web. That experience laid the foundation for my journey into senior frontend development.

Finding My Way to Web

Despite my love for mobile development, the web kept calling my name. With my eye for design, frontend felt like the perfect playground. I dove into HTML, CSS, and JavaScript—with React in 2016 becoming my game-changer. A few months later and I had landed my first full-time web dev role and never looked back.

Growth Through Challenge

Like many people, the COVID years changed the way I viewed work and life. With more time at home, I focused on learning new technologies, building side projects, and expanding my skills beyond mobile development. What started as a challenging period became an opportunity for growth, helping me become a more adaptable engineer and a lifelong learner.

These Days

Today, I work as a Senior Frontend Engineer with a passion for building scalable, user-focused applications and helping teams deliver high-quality products. My experience spans modern web platforms and React Native, giving me a practical lens for building polished experiences across browsers and mobile devices. I enjoy turning complex problems into simple, intuitive experiences while continuously growing as an engineer and leader.

Outside of work, I enjoy exploring new technologies, building side projects, sharing knowledge through writing, and spending time with friends and family. Curiosity, creativity, and continuous learning remain at the center of everything I do.
