About Enzo

Full-Stack Developer with 5 years of experience, specializing in JavaScript, TypeScript, React, and Node.js. I am involved in the design, development, and optimization of high-performance web applications, from the user interface to the APIs.

Throughout my experiences, I have participated in SaaS projects, business platforms, and critical web applications, with a focus on code quality, performance, and user experience.

My skills include:
• Front-End Development with React, TypeScript, JavaScript ES6+, HTML5, CSS3, Tailwind CSS, and Material UI.
• Back-End Development with Node.js, Express, and REST API creation.
• Implementation of automated tests (Playwright, Jest, React Testing Library) and software quality improvement.
• Performance optimization, reduction of loading times, and application maintainability enhancement.
• CI/CD integration, Git (GitHub, GitLab, Bitbucket), and Agile methodology work (Scrum/Kanban).

I have also developed complete projects including UX/UI design, database management, authentication systems, administration interfaces, online payment solutions, and custom business tools.

Autonomous, rigorous, and results-oriented, I integrate quickly into an existing team while being capable of independently managing a project. I place particular importance on code quality, best practices, and communication with product and business teams.

I am available for Front-End, Full-Stack, or web application optimization missions, remotely or on-site, with rapid skill acquisition on my clients' technical environments.
