I worked on the development of a new internet banking system using modern technologies like React and Tailwind CSS. I applied Test-Driven Development (TDD) practices and designed a hexagonal architecture, focusing on scalability and efficiency.Achievements:Performance Improvement: The developed system showed superior performance, ensuring a smoother and more responsive user experience.Scalability and Testability: The hexagonal architecture allowed for a highly scalable and easily testable system, facilitating the implementation of new features and continuous maintenance.Modularity: The modular design of the system enabled more agile and efficient implementation and maintenance, reducing development time and increasing the quality of the final product.

-Developed applications using React.js, Styled-Components, Hooks, and Local Storage, optimizing UX and performance.-Led code refactoring, applying SOLID principles to enhance maintainability and scalability.-Mentored front-end developers, raising the team's technical quality.-Implemented testing with Jest and Cypress, ensuring software robustness.-Managed version control with GIT, maintaining code integrity.-Integrated front-end with REST microservices, improving modularity.-Utilized Kubernetes and Docker for efficient deployment management.

-Implemented applications using React.js, Styled-Components, Hooks, Custom Hooks, and Local Storage, enhancing usability and performance.-Enhanced system performance and readability by rewriting parts of the application.-Mentored front-end developers on the team, raising technical quality and promoting best practices.Was responsible for maintaining and refactoring parts of the application, applying SOLID principles and clean code practices.-Provided system support to prevent bugs and avoid operational failures in the end client, also mentoring other developers.-Developed reusable components, easing maintenance and system expansion.-Led the implementation, creating custom libraries for the system and rebuilding parts of the application from scratch, improving communication between teams.
