"No amount of fire or freshness could challenge the fairytale he had stored up in his heart." — The Great Gatsby

Hello, welcome to JSagon. My name is Jhonatan. Make yourself at home and feel free to explore the site. Currently, this project serves as a hub for technological experimentation and demonstration of utilities that make everyday digital life easier.

With over 11 years of professional experience in software development, my journey has spanned from Commercial Automation and complex tax systems (NF-e, NFC-e, Sped) to the architecture of distributed systems and modern high-performance ecosystems. Currently, I hold the role of Software Architect, focusing on scalability, maintainability, and technical excellence.

🚀 Ecosystem and Technical Vision

⚡ Modern Frontend

I use Vue 3 (Composition API), Nuxt 4, and Tailwind CSS to build fluid, high-performance interfaces centered on the user experience.

⚙️ Backend and Architecture

Development is founded on NodeJS and TypeScript, strictly applying Clean Architecture principles to ensure a clear separation between the Domain, Application, and Handlers layers.

🌐 Infrastructure and Cloud

The ecosystem's sustainability is based on VPS with Nginx and integration with cloud services from AWS (Amazon Web Services), ensuring resilience and high availability.

🛠️ Featured Projects

📦 JSagon NodeJS Framework

A framework developed to simplify and speed up the creation of MVC and RESTful projects. It is a lightweight, fast, and highly customizable solution that incorporates advanced HTTP platform abstractions and innovative route builders.

📹 Live Video Chat Platform

A complete system, available for Web and Mobile, designed for real-time connections via WebRTC and Socket.IO, prioritizing performance and ultra-low latency.

🌍 JSagon Ecosystem

This project, where you are now, is the materialization of a vision for integrated utility tools, serving as a laboratory for new technologies and generative AI integration.

💡 Skills and Tools

🔹 Back-end & Architecture

NodeJS, TypeScript, PHP (Zend Framework, Laravel), Clean Architecture, Design Patterns, RESTful API development, MVC applications, and automated testing with Jest.

🎨 Front-end

Vue.js 3 (Composition API, Pinia), Nuxt 4, Nuxt UI, Tailwind CSS, Bootstrap, Semantic HTML5, and Advanced CSS3.

💾 Databases & Cloud

MongoDB (Atlas, Mongoose), MySQL, Firebird, Amazon AWS (EC2, S3, RDS), VPS management, Nginx, and version control with Git/SVN.

📚 Beyond the Code

I am passionate about books, especially in the fantasy genre. The Name of the Wind is undoubtedly one of my top recommendations. Currently, I am dedicating my reading time to topics such as Emotional Intelligence by Daniel Goleman, always seeking a balance between technical and human development.
