Hey, I'm Giovanni, a software developer and cybersecurity consultant based in Guaynabo, Puerto Rico.

I've been writing code since I was 14 – started in 1998 and haven't looked back. Over the years, I've worked across multiple disciplines: photography, video editing, motion graphics, and UX design. While I enjoy the creative aspects of technology, software engineering is where I've built my expertise and focused my career.

In 2008, I launched my first startup – a digital signage platform that ultimately didn't succeed. However, it provided invaluable lessons about entrepreneurship and product development. In 2011, I co-founded Blimp to build software for advertising agencies. We eventually pivoted to consulting, and today we design and build custom software solutions for clients across various industries.

In 2016, I founded Alias Payments (originally Gasolina Móvil) – a mobile payments platform that enabled consumers to pay for gas directly from their smartphones. As CTO until 2022, this was the most technically complex role of my career. The platform required custom hardware integrations, low-level code, payment processing systems, and PCI compliance. I also built and managed the engineering team while maintaining high product quality and customer satisfaction.

Currently, I'm running Blimp as my consulting practice, providing cybersecurity consulting services for tech startups and developing custom software solutions across multiple industries. With over 15 years of experience in software engineering, I'm passionate about solving complex technical challenges and building scalable systems.

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:
