About Luis

I am a backend developer with practical experience in real and personal projects. I work with Java Spring Boot and Python to create efficient, well-structured, and scalable solutions.

Although I'm just starting as a freelancer, I have already worked in real environments applying good architecture and development practices.
I can also handle the frontend if you need it: I use Vue 3 for web and Jetpack Compose for Android apps.
🎯 What can I bring to you?

✅ A clean and maintainable backend from the first commit
✅ Documented REST APIs ready to connect with your app or website
✅ Task or data flow automation with Python
✅ Functional interfaces if you don't have a frontend developer on your team

📦 Projects I fit best in:

Creation of RESTful APIs

Development of MVPs or projects from scratch

Improvement of existing platforms (refactoring, optimization)

🔧 Usual Stack:

Spring Boot, Python, Vue 3, Jetpack Compose, MongoDB, MariaDB, Git, Docker, Linux
