What I'm looking for

I am looking for a collaborative environment that values innovation and offers opportunities for growth.

I'm Reynaldo Souza, a Full Stack Developer with a strong focus on backend systems using Node.js and frontend development with React Native. Over the years, I have honed my skills in building scalable RESTful APIs and real-time applications utilizing WebSockets. My expertise extends to integrating both relational and NoSQL databases, including PostgreSQL and MongoDB, which has allowed me to deliver robust solutions that meet diverse client needs.

Throughout my career, I have embraced Agile methodologies and adhered to SOLID principles, ensuring that my code is not only functional but also maintainable. I have a proven track record of collaborating effectively across teams, leveraging Git for version control, and conducting thorough code reviews to enhance code quality. My experience with containerized development using Docker and automated testing with Jest further complements my technical skill set, making me a versatile asset to any development team.
