👨‍💻 Leonardo Silvatti | Personal Portfolio

Official repository for my personal portfolio. Built not just to showcase my projects and resume, but to serve as a practical demonstration of a scalable, clean, and highly performant front-end architecture.

The project adopts a strict Atomic Design approach, strong typing, automated testing, and continuous integration with external services. It is not intended for open-source contributions, serving exclusively as my digital space hosted at leonardo.silvatti.com.br.

🔭 Overview

• Purpose: Present my professional journey, resume, and technical details of both personal and professional projects.
• Design System: Modern, dark aesthetic (with subtle Vaporwave touches), focused on high contrast and accessibility.
• Performance: Aggressive asset optimization, lazy-loading for heavy libraries (like the Markdown parser), and native Next.js SSR/SSG.

🛠 Tech Stack

✨ Architecture Highlights

1. Strict Atomic Design: The interface is strictly divided into atoms, molecules, organisms, and templates. This ensures a high level of reusability and facilitates isolated testing.
2. Dynamic Integration (GitHub): The projects page consumes the GitHub API to fetch repositories, metrics (stars, forks), and README.md content in real-time.
3. Markdown Visualizer: Custom Markdown rendering engine using react-markdown and remark-gfm, featuring advanced Syntax Highlighting (Dracula theme) for code blocks imported from GitHub.
4. Error Resilience: Robust hydration handling and route fallbacks.

📝 Maintenance & Content

The data update flow was designed to require minimal friction:

• Dynamic Projects: New repositories appear automatically by adjusting tags/topics on GitHub. The content displayed on the details page is the repository's own README.md, processed securely and responsively.
• Translations (i18n): All static text on the site resides in the messages/ directory. To add or change text, edit the common.json, components.json, layout.json, or pages.json files within the respective locale (br or en).
• Resume: The physical PDF files are located at public/Resume_Leonardo_Silvatti_Silva.pdf and public/Curriculo_Leonardo_Silvatti_Silva.pdf.

🧪 Quality & Testing

Code quality is guaranteed by three pillars of verification:

1. Unit Tests (__tests__/): Focused on the individual behavior of Atoms and Molecules, executed via Jest. Structured mocks ensure the isolation of dependencies like next-intl and next/image.
2. End-to-End Tests (cypress/): Ensure that critical navigation flows (like switching languages, accessing the resume, and contact forms) work perfectly in a real environment.
3. Storybook (.storybook/): Used for Component-Driven Development (CDD). It allows visualizing all TailwindCSS variant states and validating responsiveness in isolation.
