Heitor

Hi, I'm Heitor 👋🏻

I’m Heitor, a brazilian software engineer and founder of VestCards. I like building things from scratch, talking to users, and figuring out how to make complex systems feel invisible.

I founded VestCards, a SaaS platform for students where I own the full stack, marketing, and growth. Currently, I’m at LoadSmart building ShipperGuide, a TMS for logistics. Previously, I was at Cobli, a fleet management company where I slashed fleet map load times from 10s to 80ms and built features that secured $20k in MRR.

Graduated at USP in Computer Engineering, did an exchange at Polytechnic University of Milan, and I’m starting my Master’s in Computer Science at KU Leuven. When I’m not shipping code, I’m usually playing the violin or piano.

What I build with
C Golang Kotlin JavaScript / TypeScript React Next.js MongoDB Postgres / SQL Python
