I created my personal website using Astro. Also I used it to create a blog for one of the companies I worked for.
I introduced it to my side-project using a PostgreSQL database with over 30 tables.
It’s used in all my projects since the beginning of my career. I have experience in both creating configurations and writing custom rules.
I have experience with Next.js since 2019, when I started using it in my personal projects. I also used it in a commercial project in 2020, where I was responsible for the development of the frontend application. I’m familiar with the main features of Next.js, such as server-side rendering, static site generation, and API routes.
All my projects after 2020 were written in TypeScript, as it become my go-to language for application development.

This personal project is a web application designed to help users manage their budgets by tracking income and expenses, setting financial goals, and visualizing spending habits. As the sole developer, I designed and implemented the entire application using React and TypeScript. I utilized Firebase for authentication, database, and hosting services, ensuring secure and efficient data management. The user interface was built with Material-UI, providing a responsive and user-friendly design. I integrated interactive charts to visualize spending patterns and developed a feature for generating detailed financial reports. This project is ongoing, and I continuously add new features and improvements based on user feedback.
