Freelance Data Developer - Luiz Paulo do Carmo Evangelista
Freelance Data Developer

With 13+ years in IT, I’ve led and mentored engineering teams, fostering growth and knowledge-sharing. As Director of Data Engineering at Diconium (VW Group), I’ve guided teams, recruited talent, and defined best practices. I want to be a Codementor to share my expertise in Java, Python, AWS, and data engineering while helping developers grow. I enjoy breaking down complex concepts into practical knowledge and thrive on problem-solving. Mentorship is a two-way street, and I see this as an opportunity to contribute to the tech community while continuing to learn and evolve.
