I live in Brazil with my wife Priscila and our son Rafael. Today, I work as a Staff Plus Engineer at Banco Ita\u00fa, the largest bank in Latin America. My work involves complex systems, emerging technologies, and mentoring younger engineers. On paper, it sounds like a dream job. And it is. But not long ago, this future felt completely out of my reach.<\/p>\n<h2>Breaking Through: How Open Source Became My Launchpad<\/h2>\n<p>Before all this, I spent years in low-paying jobs, unsure of how to move forward. I didn\u2019t come from privilege, and I didn\u2019t have connections. What I did have was curiosity, and a growing sense that maybe (just maybe\u2026) something more was possible if I committed to learning and didn\u2019t give up.<\/p>\n<p>The real shift came thanks to a challenge from my mother-in-law: Enroll in the university. Priscila, who was then my girlfriend, supported me fully. I enrolled at the Institute of Mathematics and Statistics at USP. It was a leap into the unknown, but I found a community that encouraged me and teachers who believed in my potential.<\/p>\n<h2>The Lightbulb Moment: C Programming As The Turning Point<\/h2>\n<div id=\"attachment_31676\" style=\"width: 409px\" class=\"wp-caption alignleft\"><img fetchpriority=\"high\" decoding=\"async\" aria-describedby=\"caption-attachment-31676\" class=\" wp-image-31676 img-fluid\" src=\"https:\/\/www.lpi.org\/wp-content\/uploads\/2025\/10\/denis-rodrigues-with-jon-maddog-hall.jpg\" alt=\"Denis Rodrigues with Jon &quot;maddog&quot; Hall.\" width=\"399\" height=\"291\" srcset=\"https:\/\/www.lpi.org\/wp-content\/uploads\/2025\/10\/denis-rodrigues-with-jon-maddog-hall.jpg 965w, https:\/\/www.lpi.org\/wp-content\/uploads\/2025\/10\/denis-rodrigues-with-jon-maddog-hall-300x219.jpg 300w, https:\/\/www.lpi.org\/wp-content\/uploads\/2025\/10\/denis-rodrigues-with-jon-maddog-hall-768x560.jpg 768w\" sizes=\"(max-width: 399px) 100vw, 399px\" \/><p id=\"caption-attachment-31676\" class=\"wp-caption-text\">Me with Jon \u00ab\u00a0maddog\u00a0\u00bb Hall.<\/p><\/div>\n<p>When I encountered C programming, something clicked. While many saw it as just another class, I saw a new world. I went deep (<em>really<\/em> deep!!!) into every concept, every structure, every line of logic. I studied through the night, filled notebooks, and soaked up knowledge from legends like <a href=\"https:\/\/en.wikipedia.org\/wiki\/Dennis_Ritchie\">Dennis Ritchie<\/a>, <a href=\"https:\/\/en.wikipedia.org\/wiki\/Linus_Torvalds\">Linus Torvalds<\/a>, <a href=\"https:\/\/en.wikipedia.org\/wiki\/Edsger_W._Dijkstra\">Edsger Dijkstra<\/a>, and <a href=\"https:\/\/en.wikipedia.org\/wiki\/Alan_Turing\">Alan Turing<\/a>.<\/p>\n<p>That passion soon led me to open source. The more I learned, the more I saw the deeper values behind the code: sharing, freedom, access. I organized events for which I reached out to global names, and to my surprise, they responded. That\u2019s how I learned about Open Beach, an event hosted by <a href=\"https:\/\/www.linkedin.com\/in\/douglasconrad\/\">Douglas Conrad<\/a> and the OpenS team. <a href=\"https:\/\/www.linkedin.com\/in\/maddog\/\">Jon \u00ab\u00a0maddog\u00a0\u00bb Hall<\/a> would be there.<\/p>\n<p>I couldn\u2019t afford the trip, so I took out a loan. It was risky, but Priscila stood by me. At <a href=\"https:\/\/wiki.debian.org\/Brasil\/GUD\/PR\/Eventos#A08-10_de_dezembro_de_2006_-_VI_Open_Beach\">Open Beach<\/a>, I met people who shared knowledge freely, with humility and generosity. And then I met maddog himself\u2026<\/p>\n<p>He listened to my ideas. He encouraged me. That one conversation shifted something inside me. If someone like him thought I had something to say, maybe the world would listen too.<\/p>\n<p>Returning home, I knew I had to keep going. It took years: grad school, certifications, job rejections. But eventually I landed a Linux sysadmin role. From there, the doors began to open.<\/p>\n<h2>Years of Effort, One Breakthrough at a Time<\/h2>\n<p>Today, I have stability, a platform, and a mission. I lead. I mentor. I speak. I build. And I will never forget where I came from. Open source changed my life. Now, I\u2019m doing everything I can to pass that change on to others.<\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/www.lpi.org\/blog\/2025\/09\/18\/from-home-lab-to-linux-certification-rodiels-journey\/\">&lt;&lt; Read the previous post of this series<\/a> | <a href=\"https:\/\/www.lpi.org\/success-stories\/\">Read more LPI success stories here &gt;&gt;<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I\u2019m Denis Rodrigues.
