About
About me
I'm João Victor, a software engineer in Fortaleza, Brazil. I studied Information Systems at the Federal University of Ceará and spent my first years at a data-science lab, building public dashboards that Ceará's government teams use every day. Today I build Quor's customer console at Getup.
I like the parts of the job that don't show up in a demo: the edge cases, the error states, the page on a slow phone. I write about how I work, more and more alongside AI agents, on the blog. And I hide easter eggs on this site, if you know where to lookstart here ↗.
How I work
04 principlesI check the page, not just the tests.
Typecheck, lint and CI can all pass on a broken page. Done means I have looked at what the user actually gets.
PostThe model can't see the page
Accessibility is a requirement, not a feature.
Screen readers, keyboard paths and contrast are part of done. On a statewide public platform that meant VLibras, too.

The unhappy path is the job.
Retries, bounces, expired links. The flows nobody demos are the ones that decide whether people trust the product.
PostSending an email is the easy part
Big changes, small safe steps.
Large rewrites go slice by slice, each step small enough to review and safe enough to roll back.
