Beyond the code, I bring a passion for leadership and team effectiveness. With 20 years of experience as a basketball coach and national instructor, I've honed my skills in motivating individuals, fostering collaboration, and guiding teams toward a shared goal. This unique background allows me to not only build robust software but also to mentor developers and facilitate the kind of transparent and collaborative environment that defines successful agile teams.

  • Team Leadership & Agile Coaching
  • Developer Mentoring & Training
  • Performance Optimization & Code Quality

I'm passionate about staying current with emerging technologies and best practices, always seeking to deliver solutions that are not just functional, but elegant and maintainable. Whether leading a development sprint or coaching a team through complex challenges, I believe that great software comes from great collaboration.

Throughout my career, I've had the privilege of working with prestigious organizations across diverse industries, including UniCredit, Gucci, Brunello Cucinelli, Banca Svizzera Italiana, Università degli Studi di Milano, Idealista, Casa.it, Pazienti.it, Italia On-line, La Cucina Italiana, and Cucine Scavolini. These collaborations have shaped my understanding of enterprise-level challenges and reinforced my commitment to delivering exceptional digital solutions that drive business value.
