Technologies I use most often

What shows up most in coursework, freelance, and personal builds.

About me

Software development student at BYU-Idaho, based in Gravataí, Brazil. I build full-stack apps, AI agents, and browser games — and ship real demos. Away from the keyboard, basketball, piano, anime, and philosophy keep me balanced: rhythm, practice, and wanting the why of things, not only the how.

Open to software development internships (2026), remote or on-site, available to start immediately. Not authorized for on-site work in the U.S. without sponsorship; open to remote contractor roles.

  • Focus on readable code, solid UX, and deployments you can visit.
  • Continuous learning across React/Next.js, Node.js, C#, and .NET.

Code, live apps, and résumés

GitHub, production URLs, API docs, and PDF résumés (EN and PT-BR).
