Luiz Fernando
Hi there! I'm Luiz, a passionate Software Engineer living in Brazil. My journey into tech started back in 2012 when I was just a kid, tinkering with my old Galaxy phone and trying to keep it up to date. I even began porting Android ROMs for old devices and joined online communities to share tips and learn together. That early spark made me fall in love with helping people and exploring the world of computing. I later immersed myself in coding at a technical school and soon landed my first internship, where I learned the basics of server maintenance and monitoring. Two years in, I stepped up as a Junior Software Engineer, developing web apps and services with VB .NET and SQL Server. Craving fresh challenges beyond legacy systems, I took on a role at a company building apps with React Native—a turning point that led me to spend three exciting years as a consultant solving complex problems. Eventually, I embraced the position of Senior Software Engineer.
