Who I am

I’m Brian, an expat who has learned that new beginnings are not just lived — they’re built. I’m passionate about discovering, learning, and understanding how things work, from the smallest details in data analysis to the big strategies behind financial markets. Curiosity, creativity, and the constant pursuit of growth drive me forward. I’m not one to settle for what I already know; I like to challenge myself, explore new paths, and absorb knowledge that helps me grow both professionally and personally. Beyond my interest in analysis and technology, I have a deep connection to art and creativity. I enjoy finding inspiration in different forms of artistic expression and bringing that same creative perspective into the way I work and solve problems. My journey has been full of changes and adaptations, which have taught me resilience, patience, and—above all—the importance of valuing every opportunity. I believe each experience is another tool to keep building the life I want. This is the story of someone who isn’t afraid to start from scratch, who puts passion into everything he does, and who knows that there’s always something new to discover.
