Hey, I'm Lucas Zimmermann👋

I'm a senior software engineer focused on backend and AI systems in Curitiba, Brazil. I build APIs, integrations and operational software with Python and TypeScript.

From November 2024 to February 2026, I founded and built AlturionX, a B2B software venture. I owned architecture, full-stack implementation and client delivery, then completed a private asset sale covering the codebase, operating platforms and client portfolio.

My public work includes AtlasOS, a Python research platform that separates financial calculations from AI narration and checks reported figures against stored engine outputs.

I bring six years of client and product engineering to my next backend, AI systems or platform role.
