Leonardo Reis Email and Phone Number
Hi, I'm Leo. I'm a Software Engineer passionate about web development, specializing in JavaScript / TypeScript, React.js, and Next.js. I’ve worked on projects focused on financial management systems, including freelancer management and payroll solutions, marketplaces, and digital banking platforms. I’ve been actively involved in front and backend development in these projects, using technologies like Nest.js (Node), PostgreSQL, and microservices.I believe that understanding the business behind a project is as important as technical skills. This enables me to contribute more effectively, delivering solutions that align with the core goals of the product. I aim not just to write code but to think strategically about its impact on the business.I’ve worked with Scrum and Kanban methodologies, which have taught me how to prioritize tasks and ensure the timely delivery of high-quality features. I always look for the best way to order development tasks to optimize efficiency and quality.Beyond coding, I enjoy acting as a mentor and facilitator within teams, helping my colleagues overcome challenges and grow professionally. In both in-person and remote settings, I often serve as a key point of communication between technical and non-technical teams, ensuring that everyone understands the purpose and progress of the work. This skill has proven invaluable in fostering a collaborative, efficient working environment.Currently, I’m focused on expanding my leadership skills to become a better leader and mentor, while enhancing my contributions to product development, helping drive both technical excellence and positive team dynamics.Let’s connect! I’m always open to discussing new challenges and opportunities.GitHub: https://github.com/leoreisdiasNotion LogBook: https://leord.notion.site/LogBook-for-Devs-00f5c6366a5e4256ac278b66788ba3ef?pvs=4NPM Packages: https://www.npmjs.com/~leoreisdias
