How I work.
Maringá, Paraná — Brazil
I'm Jonas — a senior engineer with a soft spot for editorial typography, slow-cooked side projects and code that someone six months from now won't curse me for.
Day-to-day is React, TypeScript and Next.js, but the interesting work happens between the layers — turning vague product intentions into systems that survive the meeting with real users.
Outside of client work I keep small things alive: a literary publication, a German microlearning tool, this portfolio. They give me an excuse to question my own defaults.
