Message

At Koerich Lab, I developed and maintained internal dashboards and payment checkout systems using React, TypeScript, and Next.js.

I also built and improved BFF services with Java and Spring Boot, and designed and consumed REST APIs. My work included integrating frontend applications with backend services and third-party APIs.

I developed a cross-platform mobile application using React Native, with a focus on performance and reusable components. I also worked on form validation and complex UI state management.

At Politecnico di Milano, I’m researching Large Language Models and developing prototypes to evaluate LLM-based solutions. I’m also studying cybersecurity, including secure systems design and risk analysis.
