About
I am a friendly and committed technology professional with more than 34 years of experience working in large, medium and small-scale projects across various sectors such as transportation, government, energy, and retail. I specialize in mobile, backend, and web development and am always eager to learn new concepts and improve outcomes. I believe that continuous learning and knowledge sharing are key to growth.
Outside work, I am very active, enjoying climbing, running, and biking. As a mountaineer since 2007, I have led climbing expeditions to the Andes and Himalayas, maintaining a routine of weekly training and weekend climbs. I am also passionate about music, playing multiple instruments including drums, guitars, cavaquinho, banjo, and various percussion instruments.
