About Me

TL;DR: I'm a DevSecOps engineer from Brazil, currently working as CTO at goinfinite.net.

One day, I turned on my computer and was greeted by an unexpected message:

Through a series of Google searches, I stumbled upon the fascinating world hidden behind user interfaces. At just eight years old, I delved into tools like the Windows Registry, cmd.exe, and batch files. This was my introduction to IT and sparked a lifelong passion.

Immediately, I ventured into the "security field" and soon my browser history was filled with searches about keygens, cracks, and their operations. Within a week, I was writing my first batch script and learning Pascal and Perl.

Before long, I had completely disassembled my AMD K7 computer. With 256MB RAM and a 20GB HDD, it was a gem of its time, though I was often clueless about what I was doing. Internet access was via dial-up in Brazil, making it a Herculean task to load web pages. YouTube tutorials were scarce, and I soon burned my first CPU. Despite the setbacks, my curiosity only grew stronger.

Visual Basic was the first language in which I accomplished something significant — a gaming server I released on the RaGEZONE forum, which remains active today.

Through game projects, I worked with languages like C++, LUA, and PHP, learning about TCP, DNS, and VPN. I also developed a good understanding of UX and UI design through tools like Adobe Fireworks and Photoshop.

My interest in security persisted, and I became a moderator on online forums, helping users clean their systems with tools like HijackThis and Combofix. I switched from Windows to Unix, heavily using BackTrack Linux, which later became Kali Linux. I focused on creating proofs of concept for vulnerabilities, ranging from SQLi to IDS/IPS bypassing, but I always felt a pull towards building rather than breaking.

At 14, I founded a company called Shift, developing websites with platforms like Joomla and WordPress. This introduced me to sales and gave me a new perspective on software development and business.

Back when Android was named after candy and few knew about it, I built platforms like a food delivery service and an appointments management system — precursors to today's most downloaded apps.

One project gained traction: Shift e-Lojas, an e-commerce subscription service built with WooCommerce. It grew, but I struggled with unreliable hosting. The hosting industry's weird culture of low prices, hidden limits, and poor support baffled me, so I decided to disrupt it.

With my Unix knowledge and open-source experience, I ended Shift and focused on creating a managed cloud hosting company called Infinite. We were among the first cloud companies in Brazil, making enterprise-grade services like AWS accessible to everyday users with scalable, traffic-based plans.

Infinite was tiny back then and couldn't support me financially yet. I remember using Sucuri WAF services to protect our website. I was always impressed by Sucuri's MO, so I applied for a support agent role and was hired. Quickly, I moved to senior support, handling complex cases, improving documentation, and assisting enterprise customers when things got too technical.

Eventually, I joined the Sucuri Engineering team (now part of GoDaddy), where I created and maintained tools for malware researchers, the anti-malware engine, and more. It was quite an endeavor; I was responsible for the backend, frontend, and infrastructure of dozens of projects, ranging from simple APIs to complex Kubernetes and serverless apps on AWS.

On the projects I had the opportunity to start from scratch, I experimented with new architecture patterns like Clean Architecture and DDD, which you can read a lot about on my blog. During my time at Sucuri, I also blogged about DDoS and other attacks I was familiar with.

In early 2021, I left GoDaddy and co-founded Nimbus, a software house catering to major clients in the Brazilian financial sector. There, I stretched all my technical muscles and managed teams of highly skilled DevOps engineers and developers.

Once things settled down at Nimbus, I refocused on Infinite. My goal was to create an user-friendly, secure, and powerful hosting platform. I started rebuilding Infinite's technology using Go, Clean Architecture, and DDD.

This effort led to the birth of Infinite OS, a container operating system and Infinite Ez, a user-friendly but powerful self-hosted PaaS. These are my two most exciting projects to date, encapsulating nearly 20 years of IT experience.

More to come, I hope. Thanks for reading until the end.
