About Roberto
I am Roberto Sobrinho, also known as DBA Sobrinho, and I have been working in the technology field for over 25 years, specializing in Oracle database administration. Throughout my career, I have worked in mission-critical environments, handling large volumes of data and tackling complex challenges in projects that demand high performance and reliability. My passion for technology led me to create the DBA Sobrinho blog, where I share my daily experiences, best practices, and tips for optimizing Oracle environments. I also run a YouTube channel where I post videos to help other professionals solve practical problems and improve their skills. As an Oracle ACE, I remain committed to sharing knowledge through articles, videos, lectures, and training. I believe that sharing real-world experiences is the best way to strengthen the community and help professionals overcome the challenges in the field of technology.
