About
I'm Arielton, a developer in Brazil. I work with companies here and abroad, and I handle each project from the first conversation to launch, so the person you brief is the person who builds it.
Most of my projects are sites that need to load fast and turn visitors into customers, or systems that save a team hours of manual work. When I rebuilt this site, its Lighthouse mobile performance score went from about 55 to about 98. I usually build with TypeScript, React, Next.js and Go.
This site also runs over 300 free tools I built, from calculators to file converters. They bring in visitors from search, and I build tools like them for businesses. Browse the tools
