Otavio Petry

Software Engineer

Summary

Founding Engineer. Communication graduate. I build software that drives results and explain it in terms that matter. 6 years shipping full-stack solutions from architecture to production, serving 100K+ users.

The Edge

Most engineers speak code. I speak code AND business.

Before I wrote my first line of TypeScript, I studied advertising. I learned how to frame problems, position solutions, and communicate to humans, not just machines. This isn't a fun fact from my past. It's why I:

  • -Write documentation people actually read
  • -Run discovery calls that surface real requirements
  • -Present technical decisions in business terms
  • -Ship features that solve the right problem, not just any problem

I trained in communication first. Engineering came second. That sequence matters.

Education

The Foundation

Social Communication (Advertising)

Universidade Federal do Rio Grande do Sul (UFRGS)

Mar 2009 - Jul 2018

Where I learned to think about problems before solving them. Studied persuasion, user psychology, and how to frame ideas that stick. This shapes how I approach every feature I build: what are we really solving, and how do we explain it?
