```

## About

```text
I'm a backend developer focused on Python and applied AI. I work on getting real data to language models, with per-user access control.

At CPEA, I covered the full cycle alone, from requirements to cloud architecture:

- MCP server on top of the data warehouse in Azure, with access by department through Microsoft Graph API.

- FastAPI importer: from hours per sample to 2 minutes per batch of 15 or more. In production in 28 days.

- AI-assisted proposal generator (OpenAI API and cosine similarity): from 5 to 6 hours down to about 30 minutes, for a 20-person department.

Before that, I worked with PHP backend development, monitoring and automation on AWS with Zabbix and Grafana, and Python automation.

I also like understanding things from the ground up: I implemented a RAG pipeline without LangChain, a neural network without ML libraries and Q-Learning in Haskell. My team won the XIV FATEC-BS Programming Marathon, the only one in 14 years to solve every problem, and I hold a gold medal from the Brazilian Mathematics Olympiad (OBMEP).

I hold an associate degree in Internet Systems from FATEC Baixada Santista and am studying Data Science at the same college.

I'm looking for backend and applied AI roles. Contact: joaovvscm@gmail.com
