    An accomplished IT professional, I bring over a decade's worth of experience in software development to the table. I began my career in 2011 with project-based programming, developing a strong foundation that set the stage for my future endeavors. I then advanced to a position at Accenture in 2020, expanding my knowledge in cutting-edge technologies and honing my ability to work within dynamic teams to address complex technological challenges. In 2021, I furthered my career by joining XP Inc. as a Software Engineer. This role deepened my understanding of the industry and matured my skills in development, particularly through the use of a variety of Microsoft technologies. I also held a Python Specialist position at Safra Bank, where I created innovative solutions for the IT team, gaining significant experience in Python development. Recently, I explored the TechOps field at another financial solutions company. This opportunity allowed me to leverage my SQL skills and learn about application monitoring on AWS and Java language support. Nowadays I'm working building software solutions with .NET environment for a big tech bank in Brazil. Throughout my career, I've demonstrated a commitment to continuous learning and skill enhancement. While I have an interest in management, my primary focus is on software development. I'm currently seeking opportunities that will allow me to leverage my extensive experience and skills, with a particular interest in innovative companies that value continuous learning and improvement. I believe that my solid background and passion for technology make me an asset to any team or client.
