I've been programming since I was 14 years old, and I currently have 9 years of Python development experience. I led the development of PromoVai, a complex ecommerce platform similar to iFood, covering the full development lifecycle from concept to delivery. I specialize in architecting scalable, cloud-ready solutions using Python and Django, with hands-on work in Docker, PostgreSQL, Nginx, Traefik, and React Native. I also implemented robust services atop a customized VPS infrastructure with websockets integration. I thrive in multidisciplinary teams, coordinating cross-functional deliveries and driving releases across Android and iOS ecosystems. My experience spans backend API design with Django REST Framework, CRM/HR systems, and urban mobility platforms, with a history of freelance and client-focused engagements.
