Adeonir Kohl

Hi, I'm Adeonir, and I like building things for the internet. As a frontend and design engineer, I explore ideas through prototypes, create functional and accessible interfaces, build component libraries and design systems. I especially enjoy working at the intersection of design and code, always with an eye for detail.

After more than a decade as a graphic designer working on advertising materials, books, and magazines, I moved into frontend development. Day to day, I work mainly with React, TypeScript, Next.js, and Tailwind, and I use AI agents like Claude Code and Codex across the whole cycle, from specs and planning to implementation and review. I work in English at a professional level and have collaborated with teams in Europe and the US.

Outside of work, I build a few personal projects where I design the interface and define the architecture, and get to practice backend and mobile development too.

In my spare time, I like spending time with family, collecting Hot Wheels with my son, watching TV shows and movies, and hanging out with friends.

  Artificial intelligence

  I use AI agents to plan solutions, create prototypes, and test code. I also integrate AI features into products, like the audio narration on this site.

• #

  Design systems

  I keep the component library organized and documented, so the team can build new screens to the same standard without rewriting what's already there.

• #

  Accessible interfaces

  I work on accessibility from the first component, so the interface also works with keyboard navigation or a screen reader.

  Performance

  I care about how each screen performs, especially how long it takes to load and how it responds to interactions.
