What I'm looking for

I’m looking to build scalable, maintainable software in collaborative teams, contributing across frontend and backend systems while growing in LLM applications, secure systems design, and modern engineering practices.

At Koerich Lab, I built and maintained internal dashboards and payment checkout systems using React, TypeScript, Next.js, Java, and Spring Boot. I improved BFF services, integrated third-party APIs, and focused on scalable, maintainable REST-based applications.

I’m currently expanding my software engineering practice through an international exchange at Politecnico di Milano, researching LLM applications and secure system design. I bring experience across frontend, backend, mobile development, microservices, SQL/NoSQL databases, and Agile delivery.
