Portrait of Micael Marques, with curly hair, a beard and sunglasses.

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.

four rules, no exceptions

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