Introduction

About Me

I'm Claudinei Alves, a developer focused on Data Science, Artificial Intelligence, and software development. I'm passionate about building intelligent systems and data-driven applications, using primarily Python, machine learning, and modern web development technologies. I'm currently pursuing a Bachelor's degree in Data Science and Artificial Intelligence, where I develop projects involving data analysis, machine learning models, and technological solutions for real-world problems. I constantly seek to learn new technologies and apply knowledge in practical and innovative projects.

Transparência BR API

Async REST API built with FastAPI that exposes four datasets from Brazil's Federal Transparency Portal (CGU) — corporate card spending, official travel, contracts and public bids — through versioned /v1/ endpoints. Every page fetched is normalized and stored in PostgreSQL, and stored records can be filtered by agency, period and value range.

Local-LLM Email Triage Agent

Agent that sorts incoming email into 8 semantic categories with an LLM running locally (Ollama + llama3.1), orchestrated by self-hosted n8n on Docker Compose. Prompt, categories and thresholds live in versioned YAML, and no content is sent to third-party APIs.
