AI Automation Engineer | Full Stack Developer

🚀 About Me

Automation Engineer specialized in bridging the gap between legacy enterprise systems and modern AI capabilities.

I architect production-grade automation systems that go beyond simple "no-code" workflows. By combining the orchestration power of n8n with the robustness of Python and .NET, I build scalable, fault-tolerant pipelines that handle complex business logic and AI integrations.

With a strong background as a Full Stack Developer and CTO, I bring a "software engineering mindset" to automation—implementing proper error handling, version control, and CI/CD practices often missing in standard ops roles.

  • 🌍 Mobility: Italian & Brazilian Citizen (No visa sponsorship required for EU).
  • 🏢 Current Focus: Designing LLM-driven workflows (RAG, Agents) and automating end-to-end business processes.
  • 💡 Philosophy: "Don't just automate tasks; engineer solutions."

🛠️ Technical Arsenal

My core stack focuses on Automation, AI Integration, and Backend Engineering.

Primary Focus: Automation & AI

n8n Python OpenAI Anthropic LangChain

Enterprise Backend (Solid Foundation)
