History
I began my software development journey as a self-taught learner in middle school and pursued a technical programming course in high school. After high school, I worked as a full-stack web developer and then earned a Computer Science degree, gaining valuable experience at various companies, including NIC.br. There, I specialized in full-stack web and native Android development. Later, I co-founded Simpli, a startup that grew into a successful software house, delivering diverse projects, including blockchain development. This period helped me evolve as both a developer and a leader.
