About me

I'm a software engineer with 4+ years building full-stack products and AI-automation systems. I work mainly in Python (FastAPI) and TypeScript (NestJS, Next.js, React).

I focus on LLM agents, the Model Context Protocol and n8n workflow automation. I work across the whole delivery cycle: API and data-model design, real-time systems, multi-tenant infrastructure and desktop applications.

Right now I'm building Aurora, a desktop UI library for Python with a Rust core, and working on the InvokeIA platform. I work remotely, I'm open to relocation, and I speak Spanish natively, English B2 and Portuguese A2.
