About

Hi, I’m Libardo. I design cloud architecture and privacy-first AI systems for companies across Europe, Asia, and Latin America.

As a solutions architect, my job is making the hard calls before anyone writes code: which cloud to run on (AWS, GCP, or DigitalOcean), and when sensitive data means the answer is local LLM/RAG instead of an API. I’m ISC² certified in cybersecurity, so threat modeling and zero-trust design get built in early, not patched on later.

On the side I ship my own products: an AI research workspace that runs 100% on-device, an EdTech platform with in-browser code grading, and a few native Apple apps. All privacy-first, all live in production.

I’m open to consulting, contract, and full-time work, EU-based and working remote or hybrid in the EU timezone. If you have a system that needs to scale, or data that should never leave your servers, that’s the conversation I’m best at.
