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.
