About

  • I'm Fernando Junior, a Full Stack Developer with 4+ years of experience building web products. Detail-obsessed. Design that works as well as it looks.
  • I work the full stack: UI, component architecture, and APIs. In production I ship TypeScript, React, and Next.js in a monorepo.
  • I keep inventing projects and actually finishing them. Components, interfaces, products. Rough idea in, something polished out.

Visual archive of NASA's APOD since 1995. Gallery, search, and filters on a database I own, so a specific day's image is easy to find without hitting the API.

A QR generator built my way: its own look, PIX, Wi-Fi, events and other kinds, all in the browser. No sign-up, no server.

In-browser RSVP reader: paste a long text and read one word at a time, with a fixed recognition point (ORP) and smart pacing. No account, no server, nothing leaves your browser.
