AI Orchestrator

I build complete web and mobile products: from FastAPI and AWS on the backend to React on the frontend. And I use AI agents to build faster.

About

About me

Hugo Onofri Bastit — Mar del Plata, AR — Hugo O. BastitMar del Plata, AR

I'm a full-stack developer from Mar del Plata, Argentina. I've worked in fintech, e-commerce and product. I like clear architectures, considered interfaces and things that work in production. Outside of work, I like to keep learning and build things on my own.
