Hi, I'm Patrick Priebe 👋

About me

I build efficient APIs and scalable architectures grounded in Clean Code, SOLID and Domain-Driven Design. My backend work covers message-driven integrations, secure authentication and authorization layers, observability, and optimized relational modeling — with a strong emphasis on PostgreSQL — shipped through Docker and CI/CD pipelines. On top of that backend foundation, practical experience with React and mobile gives me an end-to-end view of the application lifecycle, from data model to interface.

  • 💼 Software Development Analyst at UTC Brasil, where I started as an IT Technician and moved into development.
  • 🎓 BSc in Computer Science — Universidade de Santa Cruz do Sul (2020 – 2025).
  • 🧱 Day to day: Java · Spring Boot · PostgreSQL · Kafka · Docker, with DDD, clean layering and observability baked in.
  • 🌐 Comfortable across the stack: React, Next.js, TypeScript and Angular on the front, Azure DevOps and CI/CD on the way out.
  • 🤖 Currently exploring AI agent orchestration — multi-agent development workflows.
