I'm a Brazilian backend developer focused on building clean, well-structured REST APIs with Python. I'm currently completing my degree in Systems Analysis and Development (ADS) and actively working toward my first backend internship.

My work follows layered architectures (MVC/repository pattern), and I care a lot about writing readable, testable code with real-world tooling — Docker, PostgreSQL, JWT auth, and more.

I'm also exploring AI integration in backend systems — semantic search, local LLMs, and embeddings.

AI / ML (Exploring)

A REST API that lets users save notes and articles, then ask questions about their own content — powered by a local LLM.

• Semantic search via nomic-embed-text embeddings and cosine similarity
• Local LLM QA using Ollama + phi3:mini
• Multi-stage Docker build with non-root container, health checks, and persistent volumes
• JWT authentication, layered architecture, automated tests with pytest

A full-featured blogging backend with users, posts, comments, and role-based access control.

• JWT authentication with bearer tokens and bcrypt password hashing
• Role-based ownership — only authors can edit or delete their own content
• Layered MVC architecture with dependency injection and SQLAlchemy ORM
• Dockerized with Docker Compose

A practical task manager built with React 19 and Vite.

• Add, edit, complete, and remove tasks with a clean UI
• localStorage persistence — tasks survive page reloads
• Completion counter and congratulations message when all tasks are done
• Built with React hooks, CSS, and ESLint

Academic OOP project in Java — a shopping center store management system.

• 5 specialized store types: Alimentação, Bijuteria, Cosméticos, Informática, Vestuário — each with unique attributes
• Product management with automatic expiry date validation
• Demonstrates inheritance, polymorphism, and class hierarchies in Java
