More About Me

Software developer with a focus on web development, specialized in building modern, fast, and scalable applications. I primarily work in full-stack development using technologies such as HTML, CSS, JavaScript, TypeScript, React, Astro, and Tailwind CSS, creating intuitive and responsive interfaces.

On the backend, I develop APIs and services using Node.js, Bun, and both SQL and NoSQL databases such as MongoDB. I also have experience with Rust, as well as automation and data analysis tools like Power BI and Power Automate.

I have developed personal and academic projects where I apply best development practices, version control, and testing. I am characterized by continuous learning, logical thinking, and a strong focus on building efficient solutions.
