Hi, I’m Giovanni, a software developer, and cybersecurity consultant from San Juan, Puerto Rico.

I began writing software in 1998 when I was 14 years old. My formal education is in design, visual arts, and filmmaking. Over the years, I’ve also worked professionally as a photographer, video editor, motion graphics designer, and user experience designer, but I always find my way back to coding.

In 2008, I launched my first startup, a digital sign management platform. Although it wasn’t successful, it taught me a lot about what not to do. In 2011, I co-founded Blimp to create software for creative companies. After a few years, we pivoted to focus on consulting. Today, Blimp designs and builds world-class custom software for our incredibly smart, cool, and wonderful clients.

In 2015, I created Gasolina Móvil, an electronic payments platform that enabled consumers to pay at the pump with a mobile app. I served as the CTO until 2022. This was one of my most challenging projects, involving custom hardware, low-level code, payment processing, and security compliance, in a fast-paced work environment. It was a lot of fun.

Currently, I’m back at Blimp, doing cybersecurity consulting for tech startups and building custom software for a variety of businesses.

On this site, I try to share things that I want to remember and reference later. Posts are in English and Spanish. Here are a few of the most popular ones:
