02. about

About me

I'm a full-stack developer with over 4 years of experience designing and building scalable, secure web applications — from interactive React and Next.js interfaces to robust Node.js and NestJS backends.

These days I focus increasingly on the AI side of the stack: integrating LLM APIs, building retrieval-augmented (RAG) pipelines, and working with vector databases — while keeping the same emphasis on clean architecture and production-readiness that backend work demands.

I'm currently pursuing an MSc in Software Engineering at the Polytechnic University of Turin, after a Bachelor's in Computer Science with a 17.90/20 GPA.
