Gabriel Dos Santos

Brazilian developer

Gabriel Dos Santos

I work full-time as a software engineer, and I keep shipping after hours. A few of those projects are live. This page is the short version.

About

I’m a Brazilian developer. I spend my days writing production software, and I spend some of the rest building things I actually want to exist — pet tags, transcription, language practice.

A problem solver. Fixing software is always a challenge. I like the unglamorous parts: queues, payments, deploy, the last 10% that makes something usable.

I speak Portuguese, English, and some French. If you want the professional trail, it’s on LinkedIn.

  1. 01 Product

    Petba

    QR ID plaques for pets. Each plaque opens a public profile with photo, details, and a way to reach the owner.

    Built for the street, not a demo. Scan the tag, see the animal, get them home.

  2. 02 Tool

    letzwhisper

    Inexpensive GPU transcription. Upload audio or POST it to the API, wait your turn, download text, SRT, or JSON.

    No speed promise. The point is it gets done, and unused hours last a year.

  3. 03 Partnership

    Owlearn

    English for working professionals — daily lessons, an AI tutor, no streaks or points. A partnership with my professor, Rafael Dupont.

    Sustainable practice for people who already have a job, not a game.
