Backend Development

My primary backend focus is Java and Spring Boot, with experience designing and maintaining enterprise services and APIs. I work on modular and microservices-based architectures, with attention to clear boundaries, maintainability, reliability, and production readiness. My experience includes migrating legacy services toward more modern architectures and implementing REST APIs for complex business domains. I use Hibernate/JPA for persistence and Python when it is a good fit for automation or data-processing tasks. I also work with observability tools such as Elasticsearch, Kibana, and Grafana to monitor services and investigate production issues.

Frontend Development

Modern web applications built with React-based technologies, Next.js, Angular, and TypeScript.

Frontend Development

I build responsive web applications with TypeScript, React-based technologies, Next.js, and Angular. I use Next.js for public-facing applications and content-driven websites, including server-side rendering, static generation, internationalization, and SEO-oriented implementations. I also have experience with Angular in enterprise application contexts. My frontend work focuses on clean component architecture, maintainability, responsive design, performance, accessibility, and reliable integration with backend APIs and services.

Mobile Development

I develop native Android applications using Kotlin and Jetpack Compose, with a focus on maintainable architecture, responsive UI, and reliable asynchronous operations. At Intesa Sanpaolo, I contributed to mobile banking features in a regulated environment, working with secure-coding practices, testing, and a Java-to-Kotlin migration of core modules. I use Kotlin Coroutines for asynchronous workflows and apply modern Android development practices with attention to performance, null-safety, and code maintainability.

DevOps & Production

I work across the software delivery lifecycle, using Git-based workflows, Jenkins CI/CD pipelines, and Docker to automate testing and deployment and maintain consistent environments. I also work with production observability tools such as Elasticsearch, Kibana, and Grafana to monitor applications, investigate failures, and support reliable releases. My database experience includes both SQL and NoSQL technologies, including PostgreSQL and MongoDB, with a broader focus on building and maintaining reliable production systems.
