# Micael Marques

> Software engineer and founder of AraraHQ. I build products from zero and run what I build. Based in Juazeiro do Norte, Ceará, Brazil (07°12′S 39°18′W).

I was born in Barbalha, in the Cariri region of Ceará, Brazil. I studied Computer Engineering at IFPB in Campina Grande, where I placed first in the entrance exam. I spent seven years making other people’s products work, from a local consultancy to Serasa Experian. In 2025 I came back to Cariri and founded AraraHQ.

## How I work

- Constraint is an advantage. Little money, few people, little time. That is how lean scope is born.
- The API is the truth. If it is not in the API contract, it does not exist. The screen comes later.
- Ship fast, fix faster. Production is the only place where a product learns.
- I build what runs without me. If it needs me awake to work, it is not done yet.
