Things I've built or am building, mostly on nights and weekends.

A chat-first AI marketing agent for Brazilian small businesses. You say what you want (more people in the store) and it plans, writes and runs the campaign.
A free mentorship program that helps first-year students get into programming through real projects. Born in João Pessoa, PB; I lead it at CIn UFPE and built its website.
An agent that reads the WhatsApp messages doctors get, detects shift offers and checks them against the doctor's schedule to decide whether they can take it.
An on-call agent built with LangGraph. Given an alert, it triages, pulls metrics, logs and deploy history, plans from runbooks, asks a human before anything risky, then validates the fix and writes the incident report.
An accounting assistant: upload a PDF, Excel or CSV and chat with your financial data about revenue, expenses, taxes and trends.
Generates Instagram images and captions with AI and schedules them straight to the account. Built with a team of four; I focused on the backend.
