Hey, I'm Rawallon, a full-stack engineer in Curitiba, Brazil. I've spent six years building Python and TypeScript products in fintech, data and B2B SaaS.
I like owning a feature from the data model or API all the way to the screen. Right now that means backend and data services for an enterprise culture assessment platform, and fixing the production bottlenecks that slow them down.
On my own time I build tools I want to use: a Markdown editor, a Steam playtime tracker, a Linux screen recorder. I like learning a part of the stack I haven't touched, and I care about the small details that make software pleasant to use.
