ABOUT ME

My interest in technology started early. Whenever I see a manual, repetitive process, I cannot resist trying to automate it. That curiosity took me from iPhone board repair to notary desks and back to technology.

Today I work as a notary clerk at Cartório Gaya in Blumenau, Brazil. I found that I work well in the legal world, but I am always drawn back to technology: I try to improve or automate processes even when nobody asks.

I build software using generative AI (Claude, GPT) as my primary tool, from LLM prototypes to back-end and front-end. I do not write every line from scratch; my work is to decompose the problem, structure the instruction, and connect the pieces until the entire flow works. That is exactly the engineering I want to do in production: put AI to work solving real problems.

PROFESSIONAL HISTORY

Jul 2026 → PRESENT IN DEVELOPMENT

Founder & Builder — DocFácil

K-HUB Soluções · github.com/Kauerc10/docfacil ↗

AI ARCHITECTURE: AI PROVIDER + STREAMING

A Next.js platform that generates legal documents through conversation. I built a provider-agnostic layer (`AIProvider`) with an environment-based factory, a server-side API route (`/api/ai/generate`) that keeps secrets on the server, response streaming, and typed error handling (`AIError`). Real providers (OpenAI / Anthropic / Gemini) are pluggable without changing the rest of the app.

  • Guided chat interface with real-time document preview.
  • The AI layer is decoupled. Changing the LLM requires no front-end changes.

Cartório Gaya · Blumenau, Brazil

INITIATIVE PROJECT: ATLAS NOTARIAL

I built an automation that consumes Detran-RS endpoints to generate vehicle powers of attorney automatically, eliminating repetitive manual entry. It remains in production at the notary office. A task that took minutes now takes only a few clicks.

  • Drafting powers of attorney, deeds, and estate inventories.
  • Self-directed improvement of digital workflows.
  • General network and hardware support and diagnostics.
